Mesh analysis

Mesh analysis is a way to figure out how electricity flows through a circuit. Let's say you have a toy car that needs batteries to move. You connect the batteries with wires to the motor that powers the car. The wires and the motor create a circuit.

Now, imagine that you have many different parts in your circuit, like a light bulb, a switch, and a resistor. You want to know how much electricity will go through each part of the circuit. Mesh analysis helps you do this.

To use mesh analysis, you imagine a mesh, which is like a net, over the circuit. You draw a line around each closed loop in the circuit. Each of these lines is a mesh. So, if you have three closed loops in your circuit, you will have three different meshes.

Next, you use a set of equations to calculate how much electricity flows through each mesh. These equations use something called Ohm's Law, which says that the amount of electricity flowing through a circuit is directly proportional to the voltage (how much energy is powering the circuit) and inversely proportional to the resistance (how much something in the circuit slows down the flow of electricity).

By using mesh analysis, you can find out how much electricity is going through each part of your circuit, so you know which parts may need more or less voltage to work properly. And that's how mesh analysis helps you understand electrical circuits!
