Explanation / Answer

Given Capacitor C = 2.00 x 10^-9 F Resistance R = 2.77 k-ohms Initial charge qo =5.76 x 10^-6C a) Calculate the current in the resistor 9.00 µs after the resistor is connected across the terminals of the capacitor. The current in the resistor is I = qo *( 1/( RC) ) * e^(-t /CR) Here t = 9.00 x 10^-6s Substitute the values and do the calculation b) What charge remains on the capacitor after 8.00 µs? The charge in the capacitor is q = qo[1- e-t /(CR)] Here t = 8.00 x 10^-6s Substitute the values and do the calculation c) What is the maximum current in the resistor? The maximum current in the resistor is Io = qo /( RC) Substitute the values and do the calculation.
