ANSWER:

Problem 40

A 4.60-µF capacitor that is initially uncharged is connected in series with a 7.50-k resistor and an emf source with = 245 V and negligible internal resistance. Just after the circuit is completed, what are (a) the voltage drop across the capacitor; (b) the voltage drop across the resistor; (c) the charge on the capacitor; (d) the current through the resistor? (e) A long time after the circuit is completed (after many time constants) what are the values of the quantities in parts (a)–(d)?

Step 1 of 4

(a) Voltage across the capacitor just after connecting is zero, since the capacitor is not charged yet.
