The turbojet engine is another example of a Gas turbine engine. The working fluid is air or gas. Turbojet engine works on the principle of Newton’s third law of motion How? Just scroll down I have added and explained all the terms.

In the early 1930s there are two engineers from America (Frank Whittle) and Germany (Hans von Ohain) developed the concept independently into practical engines.

The turbojet engine is a closed cycle gas turbine engine that is used in aircraft and other industries by the burning of fuel and the use of several components like the compressor, Turbine, propeller, and more.

The apparatus consists of a release mechanism that also acts as the start switch, a switch plate that acts as the stop switch, and conducting balls. The release mechanism and the switch plate are both connected to the Student Timer.

The release mechanism and the switch plate are both connected to the Student Timer (not included). The acceleration of gravity g can be computed by measuring the drop distance and the fall time.

Electric generators, also known as dynamos is an electric machine that converts mechanical energy into electrical energy. The electric generator’s mechanical energy is usually provided by steam turbines, gas turbines, and wind turbines. Electrical generators provide nearly all the power that is required for electric power grids.

The reverse conversion of electrical energy to mechanical energy is done by an electric motor. Both motors and generators have many similarities. But in this, the article let us focus mainly on electric generators and how they convert mechanical energy to electrical energy.

The Magnetic Field Demonstrator comprises a set of four transparent plastic plates (153mm x 76mm x 6mm), each plate has a matrix of 98 (14 x 7) small circular chambers, each chamber containing an iron rod and functioning effectively as a plotting compass.

The transfer of energy and momentum from one point of the medium to another point of the medium without actual transport of matter between two points. Wave motion is classified into three different ways:

• The medium of propagation,
• The dimensions in which a wave propagates energy,
• The energy transfer

The gold-leaf electroscope is used to detect, measure and find the nature of a charge. This device works on the principle repulsion experienced between like charges.Students must take care of the fact that a gold leaf electroscope is used to detect only the presence of charges, not the quantity of the charge on the charged rod. We can find that the body is charged or uncharged.

Electric bell is based on the principle of electromagnets. When switch is pressed, electromagnet is activated and the hammer moves and hits the gong. As the hammer moves, circuit breaks and the electromagnet is disabled.

EHT, extra high tension, the accelerator supply to a cathode ray tube. This supply typically ranges from 15 kV to 35 kV, though very early television receivers used voltages as low as 4 kV. JAICO

Magnetic Field Apparatus Apparatus To Show Force On Conductor In Magnetic Field Comprising a strong U-shaped magnet and a pair of brass rails with 4 mm socket terminals.A brass axle with plastic discs is free to roll along the rails and completes the electrical contact between them.When the axle is placed on the rails between the poles of the magnet, and a power supply unit is connected, the axle rolls along the rails, away from the centre of the magnetic field.

A two-stroke diesel engine is a diesel engine that uses compression ignition in a two-stroke combustion cycle. It was invented by Hugo Güldner in 1899.

In compression ignition, air is first compressed and heated; fuel is then injected into the cylinder, causing it to self-ignite. This delivers a power stroke each time the piston rises and falls, without any need for the additional exhaust and induction strokes of the four-stroke cycle.

Wave Motion is an activity that carries energy from one place to another without actually moving any matter. In this,energy-the ability to perform work, or to exert force over distance—is transmitted from one place to another without actually moving any matter along the wave.

Van de Graaff generator uses a moving belt to collect charge on a hollow metal structure made in the shape of a globe.

In telecommunications transmission lines are used to convey signals from one point to another. The line properties become very important especially in multi-channel systems. The TLT is a unique design for experimenting with various properties of a transmission line. The unit provides the basic concepts of a coaxial line and includes all devices and accessories required to conduct the experiments.

An electronic circuit that produces a stable DC voltage of fixed value across the load terminals irrespective of changes in the load is known as regulated power supply. Thus, the primary function of a regulated power supply is to convert an AC power into a steady DC power.

Spectrum tube power supply enables the tube(s) to be placed in position but also provides protection against accidental electrical contact. A pilot light, 6-foot grounded power cord and an on/off switch are built into the unit.

In electrical engineering, low voltage is a relative term, the definition varying by context. Different definitions are used in electric power transmission and distribution, compared with electronics design. electrical safety codes define "low voltage" circuits that are exempt from the protection required at higher voltages. These definitions vary by country and specific codes or regulations.

What is a digital power supply? The primary objective of any AC/DC or DC/DC power supply or regulator is to provide a stable DC-output voltage despite changes in input voltage or load conditions.

For showing the conversion of electrical energy to potential energy by winding up a weight on a cord. One end of the 6mm steel shaft carries a 56mm diameter aluminium 'V' pulley and the other end is fitted with a cord anchoring collar.

A Van de Graaff generator is an electrostatic generator, invented by an American physicist Robert J. Van de Graaff. It uses a moving belt that accumulates charge on a hollow metal structure designed like a globe, placed on the top of a column that is insulating in nature and thus, creating a very high electric potential in the order of a few million volts.  This results in a very large electric field that is used to accelerate charged particles.

It is a device to record an object's movement by taking a spot on a paper tape at regular time intervals. A typical ticker timer is plugged into a household outlet. So the ticker cycle of the ticker timer is closely related to the frequency of the supplied household power.

Ticker timers and tape create representations of motion in a straight line. A strip of tape is attached to a moving object, such as your hand, and passed through the timer. The timer marks the tape with a dot at regular time intervals. Different speeds result in different distances between the dots.

The apparatus consists of a pair of rails with Ø 4 mm terminals. The conductor consists of a bar with plastic discs which is placed across the rails. An alnico horseshoe magnet no. 331500 (not included) is used as a magnet.

The high tension power supply, or HT power supply, is the principal power supply for the circuit in which current is produced between the anode and the cathode. It is used to transport power to large distances. Increasing or decreasing the current can reduce power losses.

The Faraday's Law Apparatus uses an alnico magnet to move toward or away the coil in the apparatus to produce electromagnetic induction. The Faraday's Law Apparatus kit contains insulated alligator clips (red/black) to connect the terminals of the coil.

The actual definition of a digital power supply refers to the digital monitoring and control of a PSU's basic functions. This concept leads to more precise regulation of the power supply, improving signal quality and efficiency.
