In this page, I'd like to talk about the circuit. Moreover, the circuit connects the voltage and current on the breadboard. if the circuit has a big current and voltage it may shock people and they may dies if they don't use safety clothes.
There are two circuits. The first one uses AC current and another one uses DC. Moreover, they use AC circuit in the Electric City. In college we study how to connect current AC/DC in the circuit. When you connect to the resistance the lead should use the circuit.
