What is Series Circuit? Definition & Calculation | Linquip
Difference Between Series and Parallel Circuits (Reference: byjus) A parallel circuit is not the same as a series circuit. A circuit with two parallel resistors would divide into two tracks, each with a resistor. When current reaches a junction, the same amount of current entering the junction must also leave the junction.
