At time t= 0, an RC circuit consists of a 18.5-V emf device, a 68.0-0 resistor, and a 140.0-μF capacitor that is fully charged. The switch is thrown so that the capacitor begins to discharge. (a) What is the time constant of this circuit? S (b) How much charge is stored by the capacitor at t = 0.5T, 2T, and 4t? q(t = 0.5T) = μC μC UC q(t = 2T) = q(t = 4T) =

In an RC series circuit, ℰℰ = 12.0 V, R = 1.07 MΩ, and C = 2.16 µF. (a) Calculate the time constant. (b) Find the maximum charge that will appear on the capacitor during charging. (c) How long does it take for the charge to build up to 20.5 µC?

Consider an initially uncharged capacitor in an RC circuit. The resistance is 20,000 Ohms and the capacitance is 500 x10• F. If the source potential being used to charge the capacitor is 15 V, how long after charging begins will the power delivered to the resistor be 25 % of its maximum value?

You take a 6.34 V battery, a 226 kQ resistor, and an uncharged capacitor to put together a series circuit. You connect the battery and after 21.2 seconds the current in the circuit has fallen to 61% of its initial value. What is the value of the capacitor in microfarads (µF)? (Enter answer as an integer.

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.
