A 100uF capacitor is initially chargcd to 10V. The capacitor is disconnected from the source that charged it, and then a 1000 Ohm resistor is connected across the capacitor, What is the total initial energy stored in this system,
Sketch the current in the circuit and the voltage across the capacitor as a function of time (if t=0 is when the resistor is connected), What is the final energy stored in the capacitor?
Where did the initial energy go?
What is the maximum current that appears in the in the circuit any time after the resistor is connected?
How much time does it take for the capacitor to discharge to half of its original charge?
