    First calculate the resistance of the 6Ohm,12Ohm parallel circuit using 1/R = 1/R1 + 1/R2. Then add that to the 8 Ohms that's in series.
    For b, use I = V/R with R being your answer to part one, and V being the 24V of the cell
    For c, use V=IR, with I being the answer to b, and R being 8 Ohms (the resistor)
