Homework Statement
Three batteries and four resistors are connected in a loop as shown (see attachment).
What is the voltage drop across the top left resistor?
Homework Equations
V = IR
The Attempt at a Solution
This is part 3 of the 3 questions for this problem. On the other two I found the current of the loop and the voltage across points a and b.
I think that all I need to do here is multiply IR (R being the value of that resistor) but that just seems too easy. Do I have to subtract it from the total voltage for the circuit or something?
