6000 joule energy is transferred by 100 W electric bulb in 1 minute. Energy is the ability to do work.
The electric bulb with power transfer an amount of energy as calculated as follows,
Given: Power of the electric bulb = 100 W
Time t = 1 minute = 60 seconds
We know that, Power =\bold{\frac{\text {Work done}}{\text {time}}}
time
Work done
\begin{gathered}\begin{array}{l}{P=\frac{W}{t}} \\ {W=P \times t}\end{array}\end{gathered}
P=
t
W
W=P×t
W=100 \times 60100×60
W = 6000 J
Energy is the ability to do work. Hence, work done is the energy.
W = E = 6000 J
