Question: A charged capacitor is discharged through a resistor. The current I (t) through this resistor, determined by measuring the voltage V R (t) = I

A charged capacitor is discharged through a resistor. The current I (t) through this resistor, determined by measuring the voltage V R (t) = I (t) R with an oscilloscope, is shown in the graph. The total energy dissipated in the resistor is 2.0 Ã— 10ˆ’4 J.
(a) Find the capacitance C, the resistance R, and the initial charge on the capacitor.
(b) At what time is the stored energy in the capacitor 5.0 Ã— 10ˆ’5 J?
