Question

What is the power consumed by a room heater which is connected across 200V and has a resistance of 20 ohm? *

1 KW

2 KW

4 KW

6 KW

​

Answer 1

Answer:

2 KW

Explanation:

hope it will help you

Answer 2

Answer:

2 KW

Explanation:

Power P = V×I

And Current I = V/R

Given

Voltage V = 200V and resistance R = 20ohm

Then I = 200/20 = 10A

Therefore Power P = 10×200 = 2000W

or P = 2 KW
