| Assertion: An electrical motor converts mechanical energy into electrical energy. |
| Reason: An electrical motor works on the principle of mutual induction. |
A) If both assertion and reason are true and reason is the correct explanation of assertion.
B) If both assertion and reason are true and reason is not the correct explanation of assertion.
C) if assertion is true but reason is false.
D) If both assertion and reason are false.
E) If assertion is false but reason is true.
Correct Answer: D
Solution :
In an electric motor, current is passed through a coil mounted in a magnetic field. Due to flow of current in the coil a torque acts on the coil which starts rotating it. Thus electrical energy is converted into mechnaical energy. It is based on a principle that current carrying coil experiences a torque in magnetic field.
