Question
The diagram below depicts an RC-circuit where C = 3.10 ?F, R1 = 16.5 ?, R2 = 11.5 ?, and V0 = 2.50 Volts.
A) What is the current through R1 immediately after the switch S is closed?
B) What is the current through R2 immediately after the switch S is closed?
C) What is the current through the capacitor immediately after the switch S is closed?
D) What is the current through R1 after the switch S has been closed for a very long time? Assume that the battery does not go dead.
E)What is the current through R2 after the switch S has been closed for a very long time? Assume that the battery does not go dead.
Capacity initially unchargedExplanation / Answer
initially charge on capcitor is zero
A)
potential difference across R1 = V = 2.5 volts
I = V/R1 = 2.5/16.5 =0 .1515
B)
V/R2 = .22
C)
current through capacitor is same as that of R2 = .22
D)
Zero
E)
Zero
