Either by the current heating a fine wire until it glows in the incandescent lamp,
by an electrical discharge exciting agas or flourescent material in gas-discharge and flourescent lapms respectively,
or by a quantum effect in the light-emitting diode.

When a light bulb is lit electrical energy is changed into light energy and?
heat energy
Is electric energy converted to heat energy or light energy?
Yes, electrical energy can be changed into thermal (heat) energy. Light is electromagnetic energy, and electricity can be changed into light energy. We know that a resistance heater changes electrical energy into thermal energy. An electric range does this, as does an electric space heater. We see electrical energy changed into light in fluorescent lights.
Where does energy leave a circuit?
I assume you mean electricity not energy. The electrical energy doesn't leave the circuit as such it is converted by a component. E.G. A bulb in a circuit will convert the electrical energy into light and some heat.
When a lightbulb is lit electrical energy is changed into light energy and?
. . . heat energy.
Into what two forms of energy is electrical energy changed into a light bulb?
batterys
Where is the energy stored in a flashlight?
Energy is stored in the battery in a flashlight. When switched off, the energy is chemical potential energy. When you switch on, chemical reactions occur, the chemical energy is changed to electrical energy in the circuit, and then electrical energy is changed to light energy in the bulb.
When the light bulb is lit electrical energy is changed into light energy and?
When lighting a light bulb, it is changed into light and heat/thermal energy.
