Question

An electric lamp of resistance 100 Ω draws a current of 0.5 A. Find the line voltage.

Answer

We can use Ohm’s law to find the line voltage:

V = I × R

where V is the line voltage, I is current, and R is the resistance of the electric lamp.

Substituting the given values, we get:

V = 0.5 A × 100 Ω

Simplifying the expression, we get:

V = 50V

Therefore, the line voltage is 50V.
