An electrical system in which components are connected end to end, forming a single path for the current to flow through is called a(n):

• A. Series Circuit
• B. Parallel Circuit
• C. Combination circuit
• D. Insulator

Answer: (A)

In a series circuit, components are connected end-to-end so there is only one path for current to flow. Because there’s a single path, the same current moves through every component, and the total resistance is the sum of the individual resistances. The source voltage is divided among the components, with each part of the circuit dropping some voltage. If any element in the loop opens the path, the entire circuit is interrupted and current stops everywhere. The description in the question—components connected end-to-end forming a single path for current—matches this behavior of a series circuit. In contrast, a parallel circuit has multiple paths for current, and each path can carry different current while sharing the same supply voltage; an insulator isn’t a circuit type.
