bulb: In a circuit, this shows if electricity is flowing by lighting up
resistor: An electrical device that resists the flow of electrical current
wire: a thin, flexible thread of metal
ammeter: A device used to measure current in a circuit
voltmeter: A device used to measure voltage, or electrical potential energy difference
cell: Supplies energy to a circuit, by pushing current from the positive to the negative end
Here is a basic circuit with a switch
This is was the circuit looks like without a switch
An this the circuit with higher voltage
