Answer 2

One watt is equal to 1 Joule/s. (option B)

• Watt, which is represented or denoted by W, is the SI unit of Power.
• Now, we know that power is defined as the rate of energy transfer work done with respect to time.
• So, power (P) can be written as $P=\frac{work (W)}{time (t)}$.
• Since the SI unit of work or energy is the joule (J), and that of time is second (s), the SI unit of power will be $\frac{joule}{second}$. It is also called Watt (W).
• Thus, one watt is equal to 1 Joule/s. (option B)
