    2. Relevant equations
    I = V/R
    E = I1R2 = I2R2 =I3R3


    3. 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 ?
