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

A

`220sqrt(2)V` average voltage.

B

220 V average voltage.

C

Voltage and current out of phase by `pi//2`.

D

Voltage and current possibly differing in phase`phi`such that `|phi|lt (pi)/(2)`.

Text Solution

Verified by Experts

The correct Answer is:
D
As the line has some resistance `(R ne 0)`, voltage and current differ in phase `phi` such that `|phi| lt (pi)/(2)`.

Power House of the Cell

A house is fitted with seven tubelights of rating 220 V, 40 W each , two bulbs of rating 220 V, 60 W each, five fans each drawing a current of 0.4 A at 220 V , and a heater of resistance 48.4 Omega . The main line power supplied to the house is at 220 V . Calculate the bill for the month of january if tubelights and bulbs are used for 6 h daily, fans for 1 h daily , and heater for 10 h daily. The electricity is to cost Rs. 2 per unit.

A building has two air-conditioners of power 2 kW each, 5 fans of power 120 W each, and 8 lamps of power 25 W each. If the supply voltage is 220 V, the maximum current that the building can draw from the supply is close to (in Ampere):
