In the circuit below, the capacitor starts out uncharged. The resistance is R = 118 Ω, capacitance is C = 0.0647 F, and the battery emf is 16.7 V. What is the charge (Q) on the capacitor at a time of t = 3.72 seconds after the switch is closed?
In a RC circuit connected to a battery, when the switch S is closed, charge on the capacitor
rises to 1 % of the final value in 2 seconds. If the capacitor is 86 μF, what would be the
value of R which will charge the capacitor? Choose the closest answer to the value you
calculated.
