What is the purpose of wires in a circuit? why do we use wires to connect power supplies to resistors or other objects on a circuit board? why can't we just use power supplies and resistors? group of answer choices to space out the circuit so the breadboard isn't overcrowded. wires are used to facilitate the flow of electrons throughout the circuit. wires are poor conductors so they will prevent anyone from being shocked. wires have high resistivity and so will prevent electrons from flowing and shorting the circuit.
