A capacitor with a capacitance of C that is initially uncharged is connected in

Question

A capacitor with a capacitance of C that is initially uncharged is connected in series with a resistor with a resistance of R and an EMF source with negligible internal resistance which provides an EMF of E.

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?

Thanks!

Explanation / Answer

part a ) capacitor acts like a straight wire V = 0

part b ) Since no voltage drop occurs across the capacitor, all the voltage drops across the resistor = E

part c ) voltage drop on capacitor is 0

Q = CV = Q = C*0 = 0

part d ) I = E/R
