Think critically: a lightbulb converts 10 percent of the electrical energy it uses into radiant energy. make a hypothesis about the other form of energy produced.

When you touch a light bulb, you can notice that the lightbulb is actually really hot. This is because some of the energy that reaches the lightbulb is transformed into heat, if 10% of the electrical energy is used to make radiant energy (light ) then the other 90% is dissipated as heat.
