Question # 1

Does the induced current depend on the resistance of the circuit?

Ans 1: Yes the induced current depend upon the resistance of the circuit.
By ohm's law
I=e/R
Thus the induced current depends on the resistance of the circuit.

Question # 1

Write two similarities and two difference between motor and generator.

Ans 1: Similarities:
1. Construction of a motor is similar to a generator.
2. In both,magnetic field is provided by an electromagnet.
Differences:
1. Generators convert mechanical energy into electrical energy while motor converts electrical energy into mechanical energy.
2. In generator,the armature coil is rotated in the magnetic field and the current is the output.While in motor,armature is connected to battery,which rotated the armature.
