Question

If circuit containing capacitance only, the current ______.

पर्याय

• is zero

• lags the voltage

• is in phase

• leads the voltage

Answer 1

If circuit containing capacitance only, the current leads the voltage.

Explanation:

For capacitive circuit,

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

it means that the current leads the emf when perfect capacitor is present in circuit.
