Lightbulbs act as resistors. Janine is building a circuit that contains two lightbulbs in parallel. One
of the lightbulbs has a resistance of 120 ohms, but the resistance of the second lightbulb is
unknown. She models the total resistance in the circuit, t, with this equation, in which r represents
the resistance of the second lightbulb.
t =
120
T + 120
