Three resistors of 2 Ω, 3 Ω and 6 Ω are connected as follows: the 2 Ω resistor is in series with a parallel combination of 3 Ω and 6 Ω. The arrangement is connected across an 18 V supply.
(i) Find the equivalent resistance of the entire circuit.
(ii) Calculate the current flowing through the 2 Ω resistor.
(iii) Determine the current through the 3 Ω resistor.
