# Question

A capacitor (5.70μF) is connected in a series arrangement with a second capacitor (2.30μF) and a 12-V battery.

(a) How much charge is stored on each capacitor?

(b) What is the voltage drop across each capacitor? The battery is then removed, leaving the two capacitors isolated.

(c) If the smaller capacitor’s capacitance is now doubled, by how much does the charge on each and the voltage across each change?

Repeat Exercise 67 assuming, instead, that the capacitors are, instead, connected in parallel. In exercise A capacitor (5.70μF) is connected in a series arrangement with a second capacitor (2.30μF) and a 12-V battery. (a) ...A wire is connected across a steady voltage source. (a) If that wire is replaced with one of the same material that is twice as long and has twice the cross- sectional area, how will the current in the wire be affected? ...The drift speed of electrons in a complete circuit, is typically a few millimeters per second. Yet a lamp 3.0 m away from a light switch turns on instantaneously when you flip the switch. Explain this apparent paradox. In a proton linear accelerator, a 9.5-mA proton current hits a target. (a) How many protons hit the target each second? (b) How much energy is delivered to the target each second if each proton has a kinetic energy of 20 ...Two copper wires have equal lengths, but the diameter of one is three times that of the other.
