    1. The problem statement, all variables and given/known data
    A battery consisting of six cells in series, each of e.m.f 1.5V and internal resistance 0.5 Ohms is connected to two 3 Ohm resistors which are in parallel. Calculate:
    a) the total parallel resistance of the combination [1.67]
    b) write down the internal resistance of the battery
    c) calculate the current drawn from the batter [1.93]

    2. Relevant equations
    I = V/R


    3. The attempt at a solution
    I didn't know where to start :(


    Thanks in advance,
    Sam
