A 2.5-F capacitor is charged to 12 V and then discharged through a 4.8 Ω resistor. What will be the current (in A) through the resistor after 20 seconds?   ASAP PLS

You have a 12-V battery, and three capacitors, C₁ = 5.67 μF, C₂ = 18.4 μF, and C3 = 16.1 μF. Wired In Series (1 of 2) Suppose you wire all three capacitors in series then connect them to the battery? (a) What is the equivalent capacitance of the three capacitors? Cseries = 3.415 HF (b) What is the charge on each capacitor? Q₂ Q3 || || μC HC HC (c) What is the voltage across each capacitor? V₁ = V₂ = | V3 = V V V

In the figure below, V = 12V, C1 = 10μF, C2 = 20μF, and C3 = 30μF. Assume the voltage source V as been connected for a long time (so all the capacitors are fully charged). (a) What is the equivalent capacitance of the entire circuit? (b) What is the charge on each capacitor if they are fully charged? (c) What is the potential difference across each capacitor if they are fully charged? (d) What is the potential energy stored in each capacitor when they are fully charged?

A 10-7-F capacitor (100 nanofarads) is charged to 100 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 8 x 10° 2. How long will it take the capacitor voltage to dissipate to half its original value on each day?

A 10 kΩ resistor and a 3 nF capacitor are connected across a 10 V battery. The time it takes for the potential across the capacitor to reach 4 V is (a)   17.5 msecs (b)   15.3 msecs (c)   12.0 msecs (d)   18.0 msecs (e)   2.85 msecs

An initially uncharged parallel plate capacitor is connected to a circuit containing a battery with emf 8-42V and a resistor, R = 4.9MQ as shown in the figure to below. The capacitor whose plates have an area of A = 7.1mm² are separated by a distance of d = 5mm and one third of the capacitor is filled with a dielectric material, K₁ = 3.5 and the rest (two thirds) is filled with another dielectric material, K₂ = 3.4. At t=0 the switch is closed. 5.4 seconds after the switch is closed the electric field within the first dielectric material (K₁) is observed to be 18 × 106 N/C. Find the charge on the capacitor at this instant (t = 5.4s) in terms of permitivity of free space €0? Express your answer using zero decimal place. R E Answer: S K1 K2

Two capacitors are connected in series and a source voltage of 75 Volts is applied across the entire series configuration. If the resistors have values 120 and 50 micro- Farads, how much charge is on the 120 μF capacitor? Express your answer in micro- Coulombs (C).
