Question

power of lamp is 60w. find the energy in S.I unit consumed by it in 1s.

Answer 1

Power = 60 W

We know ,
Power = Energy/Time
P = E/T

The SI unit for Energy is Joule ,J

So, 60 = E/1
E = 60 watt-sec

Since 1 w-s = 1 J
So, 60 w-s = 60 J

Hope This Helps You

Answer 2

According to the circumstances mention in the question that,

Power of lamp is 60w. So the energy in S.I unit consumed by it in one second will be;

To calculate the energy consumed by the parlour movie have to apply the following formula;

P(Power)= E(Energy)/t(Time)

60 = E/1

E = 60 watt/sec

But the SI unit of the power is J(joules).

And according to the mathematical unit conversion:

1watt/sec=1 joule

60watt/sec=60joules

So,the answer is 60 joules(answer.)
