Question

the device in which induced emf is statically induced is: (a) transformer (b) ac generator (c) alternator (d) dynamo

Answer 1

Answer:

a) Transformer, is the correct one

Answer 2

(a) The device in which induced EMF is statically induced is a transformer.

Explanation:

• In the statically induced EMF, the conductor will be stationary and the magnetic field will change the induced EMF.
• Therefore, a transformer is a statically induced EMF since the conductor is stationary and magnetic field changes the induced EMF.

• A transformer is used to transmit the power of electrical energy.
• The current that is transmitted in a transformer is AC.
• A transformer will not change its frequency of AC current to increase or decrease the voltage supply.
• Electromagnetic induction and mutual induction are the principles of a transformer.
