Question
A current of 0.2 amps passes through a 3 ohm resistor. The resistor is connected to a 6v battery and an unknown resistor. what is the resistance value of the unknown resistor?
R1 = 0.6 v R2 = 5.4 v R2 = 0.2amps
5.4/0.2 = 27 ohms
27 ohms ?
R1 = 0.6 v R2 = 5.4 v R2 = 0.2amps
5.4/0.2 = 27 ohms
27 ohms ?

that's what I get
I = E/R = 6/(R+3) = 0.2
I = E/R = 6/(R+3) = 0.2

Where did 5.4 come from
