Question

an electric bulb is marked with 100 watt and 230 volt how much energy is produced in 20 minutes when operated at 230 volt. PLZZZ HELP. .....WILL MARK THE BRAINLIEST. ..☺☺☺

Answer 1

Bulb doesn't produce energy. Bulb CONSUMES energy (bulb converts Electrical energy into light energy and heat energy)

Energy consumed = power in KiloWatts x Time in hours

Here Power = 100Watts or 0.1 kiloWatts

Time = 20 minutes or 0.33 hours

So Energy consumed by bulb = 0.1kW × 0.33 hour = 0.033 kiloWatt hour or 0.033 Unit

Note :

Please support by “Marking as..." if you are satisfied with answer

Answer 2

Therefore in 20 minutes the bulb will produce 20 minutes / 60 minutes * 100W * 3,600J which is about 120,000 J
