A 30 uf capacitor is put across a 12 v battery after a long, Ask an Expert

Academics

A 3.0 uF capacitor is put across a 12 V battery. After a long time (~20 time constants), the capacitor is disconnected and placed in series through an open switch, with a 200 omega resistor.

A) Determine the charge on the capacitor before it is discharged.

B) What is the initial current through the resistor when the switch is closed?

C) At what time will the current reach 37% of its initial value?
