Calculate the current flowing ina 150 Watt bulb rated 220 V.​

Answer»

<P>Answer:

0.681 Amperes

Explanation:

Given :

  • Power rating of the BULB = P = 150 watts

  • Potential difference or the voltage of the bulb = 220 volts

To find :

  • Current flowing through the bulb (I)

Formula :

Power = potential difference × current

150 = 220 × I

I = 150/220

I = 15/22

I = 0.681 Amperes

The current flowing through the bulb is EQUAL to 0.681 Amperes

More :

  • P = V²/R

  • V = I×R

  • Q = I×T
