The electrons on the negative plate eventually pass through the resistor and neutralize the charge To study the behavior of a circuit containing a resistor and a charged capacitor when the capacitor begins to discharge Previous Answers A capacitor with capacitance C is initially charged with charge q Attime t 0, a switch is thrown to close the circuit connecting the capacitor in series with a resistor of resistance R. (Figure 1) Correct Part B Figure What is the current lo that flows through the resistor immediately after the switch is thrown? Express your answer in terms of any or all of the quantities q, R, and C. > View Available Hint(s) in Submit

Explanation / Answer

b)

The charge on the capacitor is,

q = CV

C is the capacitance of the capacitor and V is the voltage across the capacitor.

V = q/C

According to Ohm’s law, current flowing through the resistor is given as,

Io = V/R

Here, V is the voltage across the resistor and R is the resistance of the resistor.

Substitute q/C for V in equation Io = V/R

Io = q / (C/R)

Io = q / RC
