MCQ
In an induction coil with resistance, the induced emf will be maximum when
  • A
    The switch is put on due to high resistance
  • ✓
    The switch is put off due to high resistance
  • C
    The switch is put on due to low resistance
  • D
    The switch is put off due to low resistance
✓

Answer

Correct option: B.
The switch is put off due to high resistance
b
An induction coil with mesistance.

Fince, there is a metiutance, a voltage drop/emp drop will be encountered. Thus, the enf will be naximum when the switch is put off due to the high mesistance.
