A capacitor that is initially uncharged is connected in series with a resistor and an emf source with E = 100 Vand negligible internal resistance. Just after the circuit is completed, the current through the resistor is 6.2×10-5 A. The time constant for the circuit is 6.7 s .
What is the resistance of the resistor?
r=ohm?
What is the capacitance of the capacitor?
C=F?
