answer in micro fahrads and coulombs

A 4.0-µF and an 4.0-µF capacitor are connected in parallel across a 25-V battery. Find the equivalent capacitance and the total charge stored on the two capacitors.

Resistors

In the circuit in the attached file Resitor.doc, determine the current in each resistor and the voltage across 200 ohm resistor.

Circuits

In Figures 1 and 2 (attached files), let R1 = 11.0 Ω, R2 = 22.0 Ω, and let the battery have a terminal voltage of 33.0 V. (a) In the parallel circuit shown in Figure 2, to which resistor is more power delivered? (b) Verify that the sum of the power (I^2R) delivered to each resistor equals the power supplied by the battery (Power = I ΔV ). (c) In the series circuit shown in Figure 1, which resistor uses more power? (d) Verify that the sum of the power (I^2R) used by each resistor equals the power supplied by the battery (Power = I ΔV ). (e) Which circuit configuration uses more power? Note: The currents are not necessarily in the direction shown for some ci... click for more

Point Charges

Two point charges each of magnitude 2.00 ìC are located on the x axis. One is at x = 1.00 m, and the other is at x = -1.00 m. (a) Determine the electric potential on the y axis at y = 0.500 m. (b) Calculate the change in electric potential energy of the system as a third charge of -3.00 ìC is brought from infinitely far away to a position on the y axis at y = 0.500 m.
