Question

If 90 w bulb connected to a circuit with potential difference of 360 V, find the current flow through the bulb

Answer 1

Explanation:

HEY MATE. ......

$given \: p = 90w \\ \\ v = 360v \\ \\we \: know \: that \: v.i = p \: \\ \\ v.i = 90 \\ \\ i = \frac{90}{v} \\ \\ i = \frac{90}{360} \\ \\ i = \frac{1}{4} \\ \\ i = 0.25a$
