Referring to a lighting system as shown in Figure 1, four light bulbs are connected to a 12 V battery. Determine:
(a) The total current supplied by the battery.
(b) The branch currents I1, I2, and I3.
(c) The resistance of each bulb.
(d) The total resistance.
(e) Verify that the total current is equal to the sum of all branch currents.
