A 5.00-MΩ Ω resistor and a 5.00-μ μ F capacitor are connected inseries with a power supply. 1) What is the time constant for thecircuit
Part B A 20.0-μ μ F capacitor has an initial charge of 100.0 μ μC. 1) If a resistance of 20.0 Ω Ω is connected across it, what isthe initial current through the resistor?
Part C A 12.5-μ μ F capacitor is charged to a potential of 30.0V and then discharged through a 65.0 Ω Ω resistor. 1) How longafter discharge begins does it take for the capacitor to lose 90.0%of its initial charge? (Express your answer to three significantfigures.) ms m s 2) How long after discharge begins does it takefor the capacitor to lose 90.0% of its initial energy? (Expressyour answer to three significant figures.) ms m s 3) What is thecurrent through the resistor at the time when the capacitor haslost 90.0% of its initial charge? (Express your answer to threesignificant figures.) mA m A 4) What is the current through theresistor at the time when the capacitor has lost 90.0% of itsinitial energy? (Express your answer to three significant figures.)mA
