Question

The rate of current drawn from the bulb having the power 440W which is connected to 220V circuit is

Answer 1

Answer:

p=440w

v=220v

I=?

A/Q

P=V*I

440=220*I

440/220=I

2=I

Answer 2

Answer:

The current drawn by bulb from the 220V source is 2 Amperes.

Explanation:

Given:

Power, $P=440w$

Voltage across bulb, $V=220V$

Current drawn by bulb, $I=?$

The general formula for electric power is given by,

$P=V*I$

Rearranging the above equation, we get,

$\implies I=\frac{P}{V}$

$\implies I=\frac{440}{220}$

$\implies I=2A$

Therefore the current drawn by the bulb from the 220V source is 2 Amperes.
