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?

Answer»


Solution :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"`
