Consider the circuit shown below which shows a battery connected to some resistors and capacitors along with some switches which will be toggled opened or closed at different times. The components are listed above. The capacitances are in microCoulombs (?C), the resitances are in Ohms (Ω), and the times are in milliseconds (msec). A stopwatch is started at time t1=0 ms. At that time, switch S1 is closed and all other switches are open and the capacitor is allowed to charge up. (a). What is the charge (in uC) on C1 at the time the stopwatch reads t2=21.6 ms? Ans: 1750 uC (b). What is the current (in mA) through R1 at t2=21.6 ms? Ans: 34.9 mA (c). What is the voltage (in V) across R1 at t2=21.6 ms? Ans: 5.58 V (d). What is the voltage (in V) across C1 at t2=21.6 ms? Ans: 19.4 V (e). What is the energy (in mJ) in C1 at t2=21.6 ms? Ans: 17.0 mJ Then, immediately at time t2=21.6 on the stopwatch, switch S1 is thrown open and switches S2 and S3 are closed (S4 remains open). (f)i.
