An RC series circuit consists of a resistor, a voltage source of 30.0 Volts, and an initially uncharged capacitor. At t = 0 seconds, the power is connected and the capacitor begins to charge. a) What amount of time does it take the capacitor to become 80.0 % fully charged if its capacitance is 470 µF and the resistance is 28,000 Ohms? b) What is the potential difference across the resistor 5.00 s after the charging begins? c) At what time is the energy stored by the capacitor 80% of its maximum value? d) What current goes through the resistor when the capacitor is 30.0% fully charged

A 100uf capacitor and a 3.6kohms resistor are connected in series. How long will it take for the capacitor to change its charge completely?

Problem 9: A capacitor is charged with a total charge of q = 5.1E-05 C.

A 107-F capacitor (100 nanofarads) is charged to 50 V and then disconnected. One can model the charge leakage of the capacitor with a RC circuit with no voltage source and the resistance of the air between the capacitor plates. On a cold dry day, the resistance of the air gap is 5x10¹3 2; on a humid day, the resistance is 8x10° 2. How long will it take the capacitor voltage to dissipate to half its original value on each day? On the dry day, it will take seconds. (Type your answer in scientific notation, using the appropriate symbol from the math palette for any multiplication. Round to three decimal places as needed.)
