Homework Statement


Find the current through each component of the circuit.


Homework Equations


Kirchhoff's laws


The Attempt at a Solution


I labeled the current through the left battery I1 and the current through the right battery I2. Therefore the current through the resistor is I1+I2. Using the voltage rule, I1+I2 = .01 A.
I have no idea how to find I1 and I2. Would current flow through both of them?

HINT: Assume that batteries are identical (i.e. have the same internal resistance).
 


So each battery contributes half of the total current?
