An electric bulb is connected to 250 volts. If the current of 0.5 A passes through it, what is the power of the bulb?

Text Solution

Verified by Experts

The correct Answer is:
Power of electric bulb is 125 W.
Given:`" Potential difference (V) = 250 V,"`
Current (I) = 0.5 A
To find: `" "` power (P)
Formula: `" "P=VI `
Calculation : `" "`From formula,
`P=250xx0.5`
`therefore" P = 125 W"`
