Question

An electric device draws a current of 5" " A when connected to a 220" " V supply. The power of the electric device is:

A.

1.1" " kW

B.

0.44" " kW

C.

110" " W

D.

440" " W

Correct option is A

Given:

  • V= 220V,
  • I=5AI = 5 \, \text{A} I=5A

Formula used:

P =  V × I

Where:

  • ‘P’ is the power (in watts, W),
  • ‘V’ is the voltage (in volts, V),
  • ‘I’ is the current (in amperes, A)

Now, substitute the values into the formula:

P= 220V× 5A= 1100W

To convert watts (W) to kilowatts (kW), you divide the power in watts by 1000:

So, for 1100 W= 1100W1000\frac{1100W}{1000}= 1.1kW​

Thus the correct answer is (A)
