A capacitor that is initially uncharged is ocnnected in series with a resistor and an emf source with ℰ = 110 V and negligible internal resistance. Just after the circuit is completed, the current through the resistor is 6.5 × 10 −5 A. The time constant for the circuit is 5.2 s. What are the resistance of the resistor and the capacitance of the capacitor?
