How does a circuit work?

A circuit works through a series of components mainly resistors, capacitors, and IC's. There are different types of IC's the main groups are AND, OR, NOR, & NAND. Those are just the basics you first learn about when dealing with electronics. These IC's work from what we call the binary code which is just a bunch of 1's and 0's. 1 is a logical high which gives you a positive voltage and 0 is a logical low which gives you no voltage. Lets say you have an and gate hooked up to a 150ohm resistor(it's used for voltage protection of your component)connected to a simple LED. In order to get this LED to have a logical high both inputs A and B have to get a high in order for your output to be high which in return allows voltage to pass through the resistor to your LED this powering your light emmitting diode. i hope this helped.
A circuit is just that a circuit of something. In electricity, it is the flow of electricity from the power source, through the wires, and back to the power source. You flip a switch, the power flows to the device, and continues back completing the circuit.
