Answer 1

Answer:

Explanation:

"If a bulb is marked 250W- 200V, then W or Watt defines the power it will consume and the second is V which means Voltage at which the bulb functions.

Now the question is how much energy is consumed one hour- then:

Energy= Power * Time

Which becomes= 250 *60 = 900000J

And the time it will take to consume 1 kWH= 1000 wh= 250V*t=

1000/250= 4 hours

Answer: 4 hours
