Bulbs A and B in FIGURE Q28.11 are identical, and both are glowing. Bulb B is removed from its socket. Does the potential difference between points 1 and 2 increase, stay the same, decrease, or become zero? Explain.
What is the equivalent resistance between points a and b in FIGURE EX28.28?
A circuit you’re using discharges a capacitor through an unknown resistor. After charging the capacitor, you close a switch at and then monitor the resistor current with an ammeter. Your data are as follows:
Use an appropriate graph of the data to determine
(a) the resis-tance and
(b) the initial capacitor voltage.
