Question

Multiple-Choice Homework Problem 15.1 Two capacitors are connected in parallel. The combination has an equivalent capacitance of CKq. If a third capacitor is added in parallel, what happens to the capacitance of the system? The capacitance increases. The capacitance decreases. The capacitance stays the same. The capacitance either increases or decreases depending on the relative size of the new capacitor and the equivalent capacitance. Multiple-Choice Homework Problem 15.2 A resistor with resistance R, battery with voltage AV, capacitor with capacitance C, and switch are connected in series. The switch is closed at t = 0. The time constant of the circuit is r. What is the current flowing in the circuit a long time after the switch is closed?

Explanation / Answer

Part 15.1

Capacitance a group of capacitors in parallel is the sum of the capacitance

Ceq = C1 + C2 +C3

whereby the capacitance increases

Correct answer a

Part 15.2

When the switch is connected to the capacitor starts charging, pass the maximum current in the circuit, after a time equal to the current decreased to e-1 of its initial value, to further increase the time the current continues to decline until when the capacitor current is zero is loaded.

correct answer a
