Question

If circuit containing inductance only, the current ______.

Options

• leads the voltage

• is zero

• is in phase

• lags the voltage

Answer 1

If circuit containing inductance only, the current lags the voltage.

Explanation:

For inductive circuit,

i = `"i"_"o" sin (omega"t" - pi/2) and "E" = "E"_"o" sin omega "t"`

it means that, the current lags behind the emf when pure inductor is present in circuit.
