The energy consumed when 5 kW power is dissipated for 2 hrs is equal to __ kJ.
We know that, Power = Energy dissipatedTime
Energy dissipated = Power×Time = 5 kW × 2 h = 5000×2×3600 J = 36000 kJ
The energy consumed when 5 W power is dissipated for 2 hrs is equal to __ kJ.
When a 0.5 kW heater operates for 20 minutes, the electrical energy consumed is equal to ___ kJ.
When a 0.5 kW heater operates for 20 minutes, the electrical energy consumed is equal to ___kJ.
Is it possible to find the electrical energy in terms of kJ if the power consumed by a toaster in 15 min is 125 W?
