Question

equivalence of 1 watt hour in si unit

Answer 1

Answer:

3600 J

Explanation:

1 watt hour is the unit of energy which is equivalent to 1 watt (W) of power used continuously for 1 hour of time.

It is not the SI unit of energy.

The SI unit of energy is Joule (J).

To convert energy from W h to J, we change the units as:

Energy = 1 watt hour

⇒ E = 1 × J/s × 60 × 60 × s

⇒ E = 3600 J

- So the equivalent of 1 watt hour in SI unit is 3600 J.
