So there is a parallel circuit with two resistors, R1 and R2, and an ammeter that are connected to a constant 30-volt source. The equivalent resistance of the circuit is 6.0-ohms. The resistance of R1 is 10.-ohms. The resistance of R2 is equal to
a) 6.0 Ω
b) 2.0 Ω
c) 15 Ω
d) 4.0 Ω
1/Req = 1/R1 + 1/R2
1/6Ω = 1/10Ω + 1/R2, solve for R2
I plugged in the values and I got 15 Ω as my answer, but my teacher marked it as wrong in my homework.
