Battery-Resistor Circuit
Conditions of Use:
No Strings Attached
Rating

Look inside a resistor to see how it works. Increase the battery voltage to make more electrons flow though the resistor. Increase the resistance to block the flow of electrons. Watch the current and resistor temperature change.
