Lumped element model

Imagine you have a big toy castle made of many smaller toy bricks. If you break down this castle, you can say that each brick is a small part of the castle. Similarly, when we talk about lumped element model, we are considering a bigger circuit made of many smaller parts called "lumped elements."

In electronics, circuits are made of different parts such as resistors, capacitors, and inductors. The lumped element model assumes that we can simplify the circuit by assuming each of these electronic parts is a single, discrete lumped element, rather than being distributed over space.

For example, let's say you have a circuit that contains a resistor to limit the flow of electricity. In the lumped element model, we would assume that the resistor is a single, discrete component, rather than being distributed over the entire circuit.

This simplification allows us to analyze the circuit more easily, as we can use mathematical equations to work out how the different lumped elements interact with each other. However, in reality, these lumped elements can have complex interactions that are not accounted for in the lumped element model.

So, think of a lumped element model as a way to simplify a circuit by breaking it down into smaller, discrete parts that can be more easily analyzed and understood.
