URGENT. As we’ve seen, for a circuit with two resistors arranged in parallel, we can calculate the total resistance in the circuit, RT, in RT=R1R2/R1+R2
(See picture for answer choices for A, ignore that one answer is selected)
Part A
Rewrite the equation to represent the resistance of resistor2,R2, in terms of RT and R1.
Part B
The total resistance in a circuit with two parallel resistors is 2 ohms and R1 is 6 ohms. Using the equation for R2, in terms of RT and R1, what is R2?
R2 is ___ ohms
Part C
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 his equation, in which r represents the resistance of the second lightbulb. t=120r/r+120 Find the INVERSE of Janines equation. r=_
Part D
Janine determines that the total resistance in her circuit is 80 ohms. Using the inverse equation modeling this situation, find the resistance of the second lightbulb. The resistance of the second lightbulb is _ohms. A)120 B)40 C)240 D)300
