Get started for freeThe tip of a flashlight bulb is touching the top of the battery in FIGURE Q28.2. Does the bulb light? Why or why not?
The battery in FIGURE is short-circuited by an ideal ammeter having zero resistance.
a. What is the battery’s internal resistance?
b. How much power is dissipated inside the battery?
The voltage across the terminals of a battery is when the battery is connected to a load. What is the battery’s internal resistance?
Bulbs A and B in FIGURE Q28.12 are identical, and both are glowing. What happens to each bulb when the switch is closed? Does its brightness increase, stay the same, decrease, or go out? Explain
