This experiment consists of modifying a circuit.
Resistance inhibits the amount of current running along the circuit.
The greater the resistance, the lower the current. The amperage of the lightbulb tells us how much energy the lightbulb requires to function. Determine the amperage of the lightbulb. You are given a circuit on which you may vary the voltage by choosing from a variety of batterys and the resistance by adding resistors to the circuit. You will then turn on the switch, allowing current to flow through the circuit.
