Solution: Capacitor combinations are the reverse of resistor combinations. That is, parallel resistor combinations (i.e., 1/R eq = 1/R 1 + 1/R 2 + . . .) have the same equivalence form as series capacitor combinations (i.e., 1/C equ = 1/C 1 + 1/C 2 + . . . ). As such, adding a capacitor to a series circuit will decrease the equivalent

To calculate the energy stored in a capacitor in two ways. REFERENCE: Section 5.2, 8.02 Course Notes. PROBLEM SOLVING STRATEGIES (see Section 5.9, 8.02 Course Notes) .
The quantitative treatment of capacitor discharge is inevitably mathematical. As a capacitor discharges through a resistor, the charge it stores Q, the pd across it V, and the current I in the resistor all decrease exponentially with time. ‘10% of the maximum value’ of the current means 0.1 of the initial current I 0
The 1000 μF capacitor is connected across an uncharged 500 μF capacitor by closing the switch S. The charge initially stored by the 1000 μF capacitor is now shared with the 500 μF capacitor. Calculate the total capacitance of the capacitors in parallel.
