Detailed explanation-1: -A series circuit has only one path for the current to flow through, whereas a parallel circuit has multiple paths.

Detailed explanation-2: -A series circuit is a circuit that has only one pathway.

Detailed explanation-3: -This is because there is only one path for the current flow. Since electric charge flows through conductors like marbles in a tube, the rate of flow (marble speed) at any point in the circuit (tube) at any specific point in time must be equal.

Detailed explanation-4: -In summary, a series circuit is defined as having only one path through which current can flow. From this definition, three rules of series circuits follow: all components share the same current; resistances add to equal a larger, total resistance; and voltage drops add to equal a larger, total voltage.

Detailed explanation-5: -The voltage across each branch is the same. There are three separate paths (branches) for current to flow, each leaving the negative terminal and returning to the positive terminal.
