Question

(a) Explain the series and parallel circuit. Three loads A, B, C are connected in parallel to a 240 volt source. Load A takes $9.6\text{ kW}$, load B takes 60 amperes and load C has a resistance of 4.8 ohms. Calculate :

(i) $R_A$ and $R_B$

(ii) Total current

(iii) Total power

(iv) Equivalent resistance. [10]

(b) Determine the voltage at each node and current through each element in the circuit given the figure by nodal voltage method : [10]
