Question

A cell of potential difference 12 V is connected to a bulb. The resistance of filament of bulb when it glows is 24Ω. Find the current drawn from the cell.

Sum

Solution

Given, potential difference (V) = 12 V

Resistance, R = 24 Ω

Therefore, current (I) = `"V" / "R"`

Or, I = `12/24` = 0.5 A
