The energy used by the 60W bulb in one second can be calculated as follows:
Energy = Power x Time
1 kJ = 1000 J
So, the energy used by the bulb in one second is:
Energy = Power x Time
1000 J = 60 W x Time
Therefore, Time = Energy / Power
Time = 1000 J / 60 W
Time = 16.7 seconds (approx)
Therefore, the 60W light bulb will run for approximately 16.7 seconds when supplied with 1kJ of energy.
Energy = Power x Time
1 kJ = 1000 J
So, the energy used by the bulb in one second is:
Energy = Power x Time
1000 J = 60 W x Time
Therefore, Time = Energy / Power
Time = 1000 J / 60 W
Time = 16.7 seconds (approx)
Therefore, the 60W light bulb will run for approximately 16.7 seconds when supplied with 1kJ of energy.
