The line the draws power supply to your house from street has

A

zero average current.

B

`220 V` average voltage

C

voltage and current out of phase by `90^(@)`

D

voltage and current possibly differing in phase `phi` such that `|phi| le pi/2`

Text Solution

Verified by Experts

The correct Answer is:
1,4
As the supply current is alternating, so average current over one cycle is zero. The line that draws power supply has some resistance, inductance and capacitance, hence voltage and current differ in phase `phi` such that `|phi| lt pi //2`
