Capacitors in Series and Parallel Explained!

In this video, we're going to talk about capacitors in series and parallel and we're going to go over some equations that you need to know and work on some problems. So, let's say if we have a battery attached to two capacitors in parallel. Let's say the two capacitors are parallel to each other. And let's use a 10vt battery. Let's call the first capacitor C1 and the second one C2. Let's say the first capacitor has a value of 100 microfarads. The second capacitor has a value of 200 microfarads. What is the equivalent capacitance of this circuit? For parallel circuits, the equivalent capacitance is simply the sum of all the capacitors connected in parallel. So it's 100 plus 200, it's 300 microfarads. And that's all we need to do to find the equivalent capacitance. Now, how much charge is stored in C1? To calculate the charge, Q1 is equal to C1 * V1. So you need to know the voltage across C1. In a parallel circuit, the voltage across every element that's parallel to one another is the same. C1 is connected directly across the battery. So it has a voltage of 10 volts when it's fully charged. And the same is true for C2. they will all have the same voltage. So V1 is 10 and V2 is 10. So now we can calculate Q1. So it's going to be C1 which is 100 microfarads or 100 * 10 - 6 micro is 10 - 6 and V1 is just 10. So Q1 is about 0.001 Kum that's the unit of electric charge. Now what about C2? What is the charge stored on C2? So we can use this equation. Q2 is equal to C2 * V2. So that's 200 * 10 - 6 * 10 volt. So it's going to store twice the amount of charge compared to C1. So it's 0.002 Kum.
