Kirchhoff's voltage law:
From Ohm's law:
, where V is voltage, i is current, and R is resistance.
Using Kirchhoff's voltage law on the left loop in a clockwise direction:
In the circuit shown in the figure (Figure 1) all meters are idealized and the batteries have no appreciate interal resistance.
Part A. With the switch S open which point is at a higher potential: a or b?
a. point a
b. point b
Part B. Find the reading of the voltmeter with the switch S open.
Va – Vb =
Part C. With the switch closed, find the reading of the voltmeter.
Part D. With the switch closed, find the reading of the ammeter.
