Potential difference is a measure of the amount of energy transferred between two points in a circuit. In a 'series' connection the components are connected end-to-end in a line to form a single path for electrons to flow. Some materials have low resistance and are conductors; others are insulators. difference between A and B stays the same because there When a charge moves through a potential difference, work is done by the power supply and energy is transferred from it to the component and/or its surroundings. It does not matter where you put the ammeter, it will give you the same reading. Notes On Potential Difference And EMF - The Fizzics Organization www.fizzics.org. Then the potential difference across both resistors Answer (1 of 6): oh Nice question ! They also use less wiring than parallel circuits. The diagram below shows the first junction in the circuit.
