How does energy get from a battery to a bulb in a circuit?

Answer 1

It gets there through a conducting path. The path is most typically comprised

of things like copper wires, but any conductor will do.

The less energy dissipated in the conducting path, the more there is available

for the bulb to dissipate.

That's why you want the path to conduct as well as possible. Silver is best.

Copper is almost as good as silver and a lot cheaper. Wet wood is a poor

choice, and dry wood is even worse. Glass is a terribe conductor.

Answer 2

In a circuit, a chemical reaction inside the battery produces a flow of electrons. These electrons travel through the wires of the circuit to the bulb, where they pass through the filament, creating heat and light energy in the process. This is how the energy from the battery is transferred to the bulb to produce light.
