Question:

Figure employs a convention often used in circuit diagrams. The battery (or other power supply) is not shown explicitly. It is understood that the point at the top, labeled €œ36.0 V,€ is connected to the positive terminal of a 36.0-V battery having negligible internal resistance, and that the €œground€ symbol at the bottom is connected to the negative terminal of the battery. The circuit is completed through the battery, even though it is not shown on the diagram.
(a) What is the potential difference Vab, the potential of point a relative to point b, when the switch S is open?
(b) What is the current through switch S when it is closed?
(c) What is the equivalent resistance when switch S is closed?
