    A battery of e.m.f. 6.0 V and internal resistance 1.0 ohms is connected to parallel resistors of 2.0 ohms, 3.0 ohms and 6.0 ohms respectively.

    Calculate:
    a) the total circuit resistance
    b) the current from the battery
    c) the p.d. across the 1.0 ohm resistor
    d) the p.d. across each of the other resistors
    e) the power supplied to the 6.0 ohm resistor
    f) the fraction of the total power wasted in the internal resistor

    Many thanks!

    What do you need help with, exactly? Show your attempt so we can see where you are going wrong.
    Do you know how to add resistors in series and parallel, for example?
    Do you know how to apply Ohm's Law?
    Do you know the formula for power in a circuit?
