In this activity, you will rearrange and solve a rational equation and find and use the inverse of a rational equation.
As we’ve seen, for a circuit with two resistors arranged in parallel, we can calculate the total resistance in the circuit, RT , in ohms, with this equation.
1.Rewrite the equation to represent the resistance of resistor 2, R2 , in terms of RT and R1.
A. R2=RTR1/R1-1
B. R2= R1 + R2/RT R1
C. R2=RT - R1/RTR1
D. R2= RT R1/R1-RT

2.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=120r/r+120
Find the inverse of Janine’s equation.
