2. Consider the circuit below. The voltage provided by the battery is 12 V; 51: S2 and 53 are switches; L l and L 2 are bulbs with resistances of E Q and 12 Q respectively. a) Is this a parallel or series circuit? b) Which type of circuit is used to operate household circuits and why? c) Consider the case when all three switches are closed, so that the circuit is fully completed. Calculate the following quantities. i. the total resistance of the circuit. ii. the current provided by the battery. iii. the voltages across L1 and L 2. iv. the currents through L l and L 2. v. the total power supplied by the battery
