- In the circuit shown in the figure, the S switch closed at t=0 and the capacitors, which are completely empty, begin to fill. Here ε=10 V, C=5 μF and R=55 Ω. What is the time constant of the circuit, τ, in units of microseconds? When t= τ, what is the total charge, in units of microcoulomb, accumulated in the capacitors?You have the circiut below with V=60 V, C-575 μF, and R-310 ks2. You move the switch to the left position and let the capacitor become fully charged. With the capacitor fully charged, you flip the switch to the right so that the capacitor is now in a circuit with resistor R. After a time 178.25 s, the charge on the capacitor has decreased by a factor of 2.7. C R V What is the average current going through the resistor in that time? Number A. What is the average power dissipated through the resitor in this time? Number W.
