E = I1R2 = I2R2 =I3R3

The Attempt at a Solution

I got 5.22 ohms for part (a), but I'm not sure how to go about calculating the amps through a specific resistor.

part b is simple. You have calculated the total resistance of the circuit. So given the voltage applied between A & B, you could calculate the current, & this much of current has to pass through the 1 ohm resistor.

for part c, do you know how current splits into each branch in a parallel resistor combination ?

thats simple..use resistor divider formula..
