We use mechanical energy in generators to move the magnet or coiled conductor continously . In that case what shall be the energy change in a generator ?

What is the energy conversion in a generator?

What is the energy change ina a solar heater?

What is meant by a change in Gibbs energy of a system?

A heat engine is a device that converts heat energy into mechanical energy. A refrigerator is a reverse heat engine. Can we decrease the temperature of a room by keeping the door of a refrigerator open? Explain.

A moving coil galvanometer is based on the magnetic effect of current. If the conductor is lying parallel to the field what will be the force?

Heat is generated in accordance with the equation H = I^2 Rt in that case What are the methods to reduce the heat generated ?

Power Station A : Potential energy > Kinetic energy > Mechanical energy > Electrical energy Power Station B : Chemical energy > Heatenergy > Mechanical energy > Electrical energy Power Station C : Nuclear energy > Heat energy > Mechanical energy > Electrical energy. Identify the above power stations A, B, and C based on the energy change taking place in them.

The generation of emf when the magnetic flux asso ciated with a coil changes is known as electromagnetic induction. Calculate the energy stored in an inductor of in ductance 50mH when a current of 2 A is passing through it.
