What is the power, in Watts, of a bulb that transfers 30 joules per second?

30 Watts

Explanation:

In Science, power can be defined as the rate at which work is done.

Mathematically, power is given by the formula;

Where,

Given that power = 30 J/secs

Since we know, work is the rate of transfer of energy. Thus, power is the rate of expending energy.

1 J/secs = 1 W

Therefore, 30J/secs = 30W.

Where, J/secs = Joules per seconds.

W = Watts.
