Answer: A circuit is said to be a parallel circuit if the electrical components are connected in a parallel configuration or their end are connected to a common point. It forms multiple loops or pathways for the current to flow. A circuit is said to be a series circuit if the components are connected in a series configuration or cascaded formation in a single line. A series circuit forms a pathway that has only one loop, therefore, the current flowing through components is the same and the voltage divides depending on the resistance of each component.
