Two resistors R1=10Ω and R2=20Ω are connected in parallel. This parallel combination is then connected in series with a 5Ω resistor to a 30V battery having negligible internal resistance.
(i) Draw a neat circuit diagram showing the given arrangement.
(ii) Calculate the equivalent resistance of the parallel branch.
(iii) Find the total resistance of the entire circuit.
(iv) Determine the current supplied by the battery.
