Thermal Power Station A thermal power station is a power plant in which the prime mover is steam driven. The operation of a thermal power station is such that the water is heated first, and turns into steam. This steam is used for rotating a steam turbine which drives an electrical generator. After passing through … Read more
Why don’t we use copper wire as a fuse wire Fuse is a Safety device which protects an electrical device from fault. Whenever there is a fault, a short circuit current will flow that leads to the generation of high heat. This heat will damage the electrical appliance if the circuit does not open in … Read more
Resistance box The box which contains the resistors which can cover a wide range of values for estimating and comparing the resistance is known as the resistance box. Features of Resistance box The accuracy of the resistance box is very high. The main application of the resistance box is to control the specific value of … Read more
A thermal conductivity gas analyzer is used to measure the chemical purity of a gas. The working of this type of analyzer is based on the difference in heat conductivity among gases. Fig. 1 shows the Basic thermal conductivity gas analyzer circuit. It is a Wheatstone bridge formed with two sensing resistors acting as balanced legs … Read more
The neutrons have the following property as they do not carry any charge. It is very difficult to detect neutrons. So, indirect methods are employed to detect neutrons. This consist of an arrangement where alpha or beta particles or gamma-rays are produced by colliding neutrons with a certain nuclear material. Indirect Method to detect Neutrons … Read more
A microphone is a transducer that converts sound into an electrical signal. In other words, a microphone is a special type of pressure transducer converting acoustic energy (pressure waves) into electrical energy. A microphone is nicknamed as mic or mike. The sensitive transducer element of a microphone is called its element or capsule. The sound is … Read more
In this article, we will learn about hygrometers and its types. Let’s begin with the definition of the hygrometer. Hygrometer A hygrometer is an instrument that measures the humidity directly. Now discuss some terms. Humidity It is the measure of water vapour present in a gas or environment. It is measured in relative, absolute humidity or … Read more
Rechargeable batteries are those batteries that can be recharged again after discharge. You can find these batteries in your cordless tools, laptops, computers, cordless phones, and smartphones, etc. Rechargeable Batteries are also called as Secondary batteries. Rechargeable batteries are of four basic types: Nickel-cadmium (Ni-Cd), Nickel metal hydride (Ni-MH) Lithium-ion (Li-Ion) Lithium polymer (Li-Po) These batteries … Read more
Power quality refers to maintaining the near sinusoidal waveform of power distribution bus voltages and currents at rated magnitude and frequency. Power quality describes the extent of variation of the voltage, current, harmonics, and frequency of the power system. The poor power quality effects industrial competitiveness drastically and thereby impedes our efforts to turn into … Read more
