Question

If 100 J is the energy required for an appliance to run per second, then what is the power consumed by it in watts, if it operates at 220V?

• A. 22 W
• B. 22000 W
• C. 100 W
• D. Data insufficient

Answer 1

The correct option is C

100 W

Given, energy required to run an appliance = 100J.
Also, it is mentioned that the energy required for 1 second is 100 J.

Power = Energy required per unit time

$\Rightarrow Power$ $=\frac{100}{1}=100W$
