Two 110-volt storage batteries are connected as shown in the attached picture. The switch has 3 positions: UP, NEUTRAL and DOWN. Based on this information, answer questions 1-3
1. With the switch in its UP position, the voltmeter reading is
A. 110V B. 220V C. zero D. none of the above
2. With the switch in its DOWN position, the voltmeter reading is
A. 110V B. 220V C. zero D. none of the above
3. With the switch in its NEUTRAL position, the voltmeter reading is
A. 110V B. 220V C. zero D. 165V
The answers given is 1-A, 2-B, and 3-C, I think these are the correct answers.
Can't seem to figure out this seemingly simple problem, maybe I'm looking at it from the wrong perspective.
for question #1 with the switch in the up position the way I see it is the volt meter would be connected to the positive to positive and negative to negative ends with no current and 110 volts
for question #2 the circuit would have a current from the + end of one battery to the - end of the other producing a current and a series connection making 220 volts
for question #3 I don't get why the volt meter would read zero as to me it looks identical wether the switch is down or neutral.
Please help me understand this as I'm clearly missing something here.
Thank you
