A- Find the charge on the capacitor at t = 30 B- Find the voltage on the capacitor at t = 50 C- How much energy is stored in the capacitor by this current?Suppose that we have two 100-μF capacitors. One is charged to an initial voltage of 50 V, and the other is charged to 100 V. If they are placed in series with the positive terminal of the first connected to the negative terminal of the second, determine the equivalent capacitance and its initial voltage.

The resultant capacitance 2/3 C Can be obtained by using them ? a)Two in parallel and third in series with this combination b)All in parallel c)All in series d)Two in series and third in parallel across this combinationTo measure the capacitance C of a capacitor, you attach the capacitor to a battery and wait until it is fully charged. You then disconnect the capacitor from the battery and let it discharge through a resistor of resistance RR. You measure the time T1/2 that it takes the voltage across the resistor to decrease to half its initial value at the instant that the connection to the capacitor is first completed. You repeat this for several different resistors. You plot the data as T1/2 versus R and find that they lie close to a straight line that has slope 9.00 μF. What is the capacitance C of the capacitor?
