The energy transfer diagram represents the energy of a light bulb.
An illustration of a very wide arrow with a light bulb at the tail labeled electrical energy ? J. The arrow breaks into a small arrow going straight labeled light energy 20 J and a much larger arrow curling away labeled heat 100 J.
How much electrical energy is involved in this transformation?
60 J
80 J
100 J
120 J

120 J
Explanation: energy is conserved, so electrical energy in = light energy out + heat energy out = 20 J + 100 J = 120 J.
