घ एक बिजली के हीटर कितनी ऊर्जा यह 10 घंटे में इस्तेमाल कर रहा है 1500w दर्जा दिया है

Energy consumed by an electric heater can be obtained with the help of the expression, P= W/T Where, Power rating of the heater, P= 1500 W = 1.5 kW Time for which the heater has operated, T= 10 h Work done = Energy consumed by the heater Therefore, energy consumed = Power — Time = 1.5 — 10 = 15 kWh Hence, the energy ...

Answer 2

$\huge\mathfrak\red{ANSWER}$

The relation between power and energy is

Energy = Power x Time

If, Power = 1500 Watt, Time = 10 Hours

Then,

Energy = 1500 Watt x 10 Hours = 15000 Watt-hr

...........................or...................

Power= 1500w=1500/1000=1.5kw Time=10 hours Energy=power×time 1.5×10 =15kWh.
