1. The problem statement, all variables and given/known data I need to find the equivalent resistance of the network outside the battery, and the current in resistor R2. the picture of my circuit is attached. R1= 10 ohms R2 = 6 ohms R3 = 5 ohms R4 = 30 ohms 2. Relevant equations series Req= R1+R2... parallel 1/Req= 1/R1+1/R2.... 3. The attempt at a solution I have a lot of trouble sseing this picture. i think is this: R2-4 = 36 ohms R1-3 = 1/(.3)= 3.333 ohms Req= 36 + 3.33 = 39.333 ohms is it right how i split them? and would it the current trough resistor 2 just be: V=IR 30/6 = 5 Ampere ????
