Two identical resistors (R) are connected in parallel and then wired in series to a 50 Ω resistor. If the total equivalent resistance is 71 Ω, what is the value of R?
Express your answer using two significant figures.
Homework Answers
Resistance of the identical resistors = R
Resistance of the resistor connected in series with the
identical resistors = R1 = 50 
Equivalent resistance of the circuit = Req = 71
Equivalent resistance of the identical resistors in parallel connection = R2
R2 = 0.5R
Now R1 and R2 are in series connection to form the equivalent resistance.
Req = R1 + R2
71 = 50 + 0.5R
R = 42
Value of R = 42
