Question

An electric lamp is labeled 12 V, 36 W. This indicates that it should be used with a 12 V supply. What other information does the label provide?

Answer 1

Explanation:

As per the question,

Given data for an electric lamp:

Voltage = 12 V

Power = 36 W

Formula used:

Power = Voltage × Current

∴ Current supplied = 36/12 = 3 A

So from here we can conclude that the current supplied in an electric lamp is 3 A.

As the power supplied is 36 W that means energy consumed by an electric lamp at the rate of 36 J/s.
