CONCEPT:

Inductors: The coils of wire that are wound around any ferromagnetic material (iron cored) or wound around a hollow tube that increase their inductive value are called inductors.

  • The inductance (L) is measured in Henry (H) and the instantaneous voltage in volts.
  • Rate of instantaneous voltage is given by (v = L di/dt)

 

Analysis:

By integrating the voltage we will get the current,

the voltage is a rectangular function hence the current will be a ramp function. 

Hence, option 1 is correct.
