COMPLETING A SIMPLE CIRCUIT
AA Battery 1.5 volts powers flashlight bulb
The negative terminal of the battery pushes electrons towards the positive terminal which attracts the electrons. This current travels across the bulb filament where resistance causes filament to heat up and glow. Bulb is lit when circuit is completed.
