Answer #1

The total change in voltage experienced by the charge during this journey = Vf - Vi

= 0 V ; (Vf = Vi)

because charge is coming back to the same point after traversing through bulb.

Answer : E) 0V

    A 12-volt battery is connected to two light bulbs, as drawn in Figure 1. Light bulb 1 has resistance 3 ohms, while light bulb 2 has resistance 6 ohms. The battery has essentially no internal resistance, and all the wires are essentially resistanceless, too. When a light bulb is unscrewed, no current flows through that branch of the circuit. For instance, if light bulb 2 is unscrewed, current flows only around the lower loop of the circuit, which consists of...
