Question

iPad 8:57 PM 1 11% C Exercise 18.39 MasteringPhysics A 2.6 M resistor is connected in series with an initially uncharged 0.35 F capacitor. This arrangement is then connected across four 1.5-V batteries (also in series) Part A Part complete What is the maximum current in the circuit? Express your answer using two significant figures. Imax= 2.3x10-6 A Submit Correct Part B Part complete When does it occur? Express your answer using two significant figures. If the answer is infinite, enter infinity tr=0s Submit Correct

Explanation / Answer

Here,

for the time costant ,

T = R * C

T = 2.6 *10^6 * 0.35 *10^-6

T = 0.91 s

part C)

for the current percentage

I/Io = e^(-t/T)

I/Io = e^(-2.5/0.91)

I/Io = 0.0641

I/Io = 6.4 %

the current in the circuit will be 6.4 %
