What is meant by Transfer of Charge Transfer of Charge Electric charge can be transferred from a charged object to another through a metal conductor. A device working on this principle is the electroscope, which is used to detect and measure electric charge. It consists of two very thin metal strips (called leaves, because they are very thin) connected to a metal knob through … [Read more...] about What is meant by Transfer of Charge

Relationship between Energy Transferred, Current, Voltage and Time
Relationship between Energy Transferred, Current, Voltage and Time The potential difference or voltage, V across two points is defined as the energy, E dissipated or transferred by a coulomb of charge, Q that moves through the two points. Therefore, potential difference,Current is the rate of charge flow. Therefore, the total charges that flow through the two points is … [Read more...] about Relationship between Energy Transferred, Current, Voltage and Time

What is the Working Principle of AC Generator
What is the Working Principle of AC Generator AC Generator Construction of an ac generator : It consists of a rectangular coil of insulated copper wire. This coil is placed in a magnetic field between the poles of a strong permanent horseshoe magnet. This magnet is known as the field magnet. In actual practice, a large number of turns of the insulated copper wire are suitably … [Read more...] about What is the Working Principle of AC Generator
