Question

using 1 unit of electricity how long can you listen to a transistor radio of power 1 watt

Answer 1

Nice ques bro

1 unit = 1kwh
. . . = 1000 watt hours

I can listen it for 1000 hours

Answer 2

Answer: 1000 hr.

Explanation:

It is known that 1 unit is equal to 1 kWhr. It means that 1 unit will be consumed when one kW will be used in 1 hour. So, that means a transistor radio consuming a power of 1 watt in an hour need to consume more 1000 watt to reach 1 kW.

As it consumes 1 watt in an hour, so it will take 1000 hours to reach 1000 kW. Thus, the transistor radio can be listened for 1000 hours in 1 unit of electricity.
