The peak current is given by so (b) [3pt] When the switch is closed, a current of 0.10 A flows initially.
After the switch has been closed a long time, the capacitor reaches a
maximum charge of 25 C. What is the
time constant? When the switch is first closed,
When the capacitor is fully charged,
The time constant is then E, so and
with E, so E .
