Problem:
Three resistors, values 35, 45, and 85 ohms, are connected in parallel across a 35 V battery. What is the current through the 35 ohm resistor?
Attempt:
R total = 35+45+85 = 165
I total = 35V/165ohms = .2
I for 35 ohms = 35V/35 ohms = 1
I'm not sure if this is right or not, but it doesn't seem right to me. I understand how to get the total current, but I'm no sure how to get it for only 1 resistor in a parallel circuit.
