Question
Relate watt to joule.
✓
Answer
As we know that $\text{Power}=\frac{\text{Work}}{\text{Time}}$ $\text{watt}=\frac{\text{joule}}{\text{second}}$ So if the time is taken as unity then we can define watt in terms of joule. Therefore, One watt power is equal to one joule work when the time taken is unity.
