(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

a 50 ohm resistor, an unknown resistor R, a 120 volt source and an ammeter are connected in a compelete circuit. the ammeter reads 0.50 ampere

1)calculate the equivalent resistance of the circuit

2)determine the resistance of resistor r

2. Relevant equations

a = 0.50 A

v = 120

r1 = 50 ohm

r2 = ?

R = R1 + R2 + R3 + ...

3. The attempt at a solution

the problem is a series circuit so how do i know the other resistance if i know the first one?
