Immittance is a scientific term that describes how well electricity can flow in a system, like wires, circuit boards, and other electrical components. Think of it like a big pipe. This big pipe is made up of all the wires and electronics that carry electricity. The bigger the pipe, the more electricity can flow, and the better the system can work. So when scientists and engineers talk about immittance, they're talking about how big and open the pipe is - how easily electricity can flow.
