Question

an electric bulb is connected to a 22 o v generator. the current is 2 A. what is the power of the bulb

Answer 1

Power of the bulb = 440 W

Given

An electric bulb is connected to a 220 v generator. the current is 2 A

To Find

Power of the bulb

Formula Applied

$\bf \pink{\bigstar\ \; P=VI}$

where ,

• P denotes power
• V denotes potential difference / voltage
• I denotes current

Solution

Given ,

• V = 220 V
• I = 2 A
• P = ? W

Apply formula ,

$\bf \green{\bigstar\ \; P=VI}\\\\\rm \to P=(220)(2)\\\\\rm \to P=440\ W$

So , Power of the bulb = 440 W

Answer 2

Answer:

Power of the bulb = 440 W

Given

An electric bulb is connected to a 220 v generator. the current is 2 A

To Find

Power of the bulb

Formula Applied

\bf \pink{\bigstar\ \; P=VI}★ P=VI

where ,

P denotes power

V denotes potential difference / voltage

I denotes current

Solution

Given ,

V = 220 V

I = 2 A

P = ? W

Apply formula ,

\begin{gathered}\bf \green{\bigstar\ \; P=VI}\\\\\rm \to P=(220)(2)\\\\\rm \to P=440\ W\end{gathered}

★ P=VI

→P=(220)(2)

→P=440 W

So , Power of the bulb = 440 W
