A 5.00-½F capacitor that is initially uncharged is connected in series with a 7.00-k? resistor and an emf source with E=135 V and negligible internal resistance. (a) Just after the circuit is completed, what is the voltage drop across the capacitor? =___V (b) Just after the circuit is completed, what is the voltage drop across the resistor? =___V (c) Just after the circuit is completed, what is the charge on the capacitor? =___C (d) Just after the circuit is completed, what is the current through the resistor? =___A (e) A long time after the circuit is completed (after many time constants) what are the values of the quantities in parts (a) ½ (d)?

Explanation / Answer

Capacity = C = 5.00 uF

Resistance = R = 7000 ohm

emf of source = E=135 V negligible internal resistance.

A)Just after the circuit is completed, the voltage drop across the capacitor is zero

B) Just after the circuit is completed, the voltage drop across the resistor is135 V

C)Just after the circuit is completed, the charge through the resistor is 6.75 *10^-4 coloumbs

D) the current through the resistor is zero after long time

E) A long time after the circuit is completed the valuesof the quantities in parts (a)-(d) are

A) After long time,the voltage drop across the capacitor is 135 V

B) After long time,the voltage drop across the resistor is zero

C) After long time,the charge through the resistor is zero

D) After long time,the current through the resistor is zero
