A 5.00 micro farad capacitor that is initially uncharged is connected in series

Question

A 5.00 micro farad capacitor that is initially uncharged is connected in series with a 6.90 kilo-ohm resistor and an emf source with Emf= 175 V 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?

Explanation / Answer

a) just after charge across cap is zero

V = 0

b) VR = Emf = 175 V

c) charge is zero

d) I=V/R

= 25.3623 mA
