Question
Consider the circuit shown in (Figure 1) . The batteries have emfs of E1=9.0V and E2=12.0V and the resistors have values of R1=28?, R2=63?, and R3=33?.
Determine the magnitudes of the currents in each resistor shown in the figure. Ignore internal resistance of the batteries.
Express your answers using two significant figures separated by commas.
Determine the directions of the currents in each resistor. Ignore internal resistance of the batteries.

I1 right, I2 left, I3 up I1 left, I2 right, I3 up I1 left, I2 right, I3 downI1right, I2 left, I3 down
Explanation / Answer
E2>E1,SO CURRENT I1 IS PASSING FROM E1 AND I2 CURRENT IS PASSING FROM E2.BOTHARE MEETING FROM R1 AND R3 WILL GIVE I CURRENT PASSING THROUGH R2.IT DIVIDES AT NODE WILL GIVE I1 CURRNTAND I2 CURRENT.
