500
Name the components (parts) to an electric circuit.
power source (battery), conductors (wire), load (light bulb)
500
If you have two batteries and one light bulb or one battery and one light bulb, which will have a stronger load (light)?
the two batteries will have a stronger load because there is double the power
500
Electrons leave the negative end of the battery, electrons flow through the wire, electrons flow through the light bulb and cause the wire to get hot and glow, electrons leave the light bulb and enter the wire toward the positive end of the battery, electrons flow into the positive side of the battery.
This is what type of circuit?
simple circuit
