Concept

Problem: A 4.80-µF capacitor that is initially uncharged is connected in series with a 7.40-kΩ resistor and an emf source with ε = 100 V and negligible internal resistance.A. Just after the circuit is completed, what is the voltage drop across the capacitor?B. Just after the circuit is completed, what is the voltage drop across the resistor?C. Just after the circuit is completed, what is the charge on the capacitor?D. Just after the circuit is completed, what is the current through the resistor?

FREE Expert Solution

A.

The voltage drop across the capacitor is calculated just after the circuit is completed.

The voltage drop across the capacitor is then equal to zero just after the circuit is completed.
