Question

Prelecture Exploration: Parallel Combination of Capacitors Kylie wants to be an electrical engineer, so she wants to gain a better understanding of capacitors. She asks her study partner, Blake, if he wants to spend some extra time learning about parallel combinations of capacitors, and he agrees. They use this simulation to help them The friends can use the sliders to adjust the capacitance and battery voltage, Δν, and observe the effect on the charges on and voltages across the capacitors, as well as the equivalent capacitance, Ceq. To add a third and fourth capacitor in parallel, they can click on the "add capacitor" button. They note that in the simulation, dV1 is the voltage across C1, and AV2 is the voltage across C2 add capacitor C2 capacitance C2 AV2 Q2 AV2-2.0 V capacitance C1 1 pF AV1 Q1 21-2.0 pC 10 voltage 2 V 20 C2.0 pF Click here to open the simulation in a new window Part 1 of 10-Relationship among V1, V2 and V With only two capacitors in parallel, keeping Δν and C1 constant and varying C2, what relationship can Blake say exists among Δν1, Δν2, and Δν?

Answer 1

Here we know that capacitors C1 and C2 are in parallel in the circuit with the input voltage and voltage across each capacitor is same as that of input voltage due to parallel combination of capacitors.

Hence voltage across each capacitor should be the same.

So,

$\Delta V1=\Delta V2=\Delta V$ is the correct option.
