An electric bulb is connected to 200 volts if the current of passes of 0.5 passes through it what is the power of the bulb |
|
Answer» Answer: We know that, power is BASICALLY work done in UNIT time. That is, Power=work/time And, work=potential different × charge And, charge= I×t (current passing through a conductor in unit time) Therefore, power=(potential difference×charge)/(charge/current) =potential difference×current =200V × 0.5A 100watt. |
