Series Circuits
Series circuits are sometimes called cascade-coupled or daisy chain-coupled. In series, the same current passes through all the components in the series. It has moe than one resistor (anything that uses electricity to do work). An ammeter located anywhere in the circuit would measure the same quantity. An ammeter is a measuring instrument used to calculate the flow of an electric current in a circuit.
In a series circuit, there’s only one pathway that the current can get because resistors are arranged in a chain. Through each resistor, the current is the same, so you would find the total resistance of the circuit by adding up the resistance of each resistor.
