Question

Is one joule per second equivalent to one watt?

Answer 1

Power

1. Power is defined as work done per unit of time.
2. The SI unit of power is Watt.
3. Mathematically, $P=\frac{W}{T}[whereP=power,W=Workdone,t=timetaken]$
4. The SI units of work and time are Joules and seconds, respectively.
5. So, $1W=\frac{1J}{1s}$

Hence, One Watt was defined as a power of 1 Joule per second.
