An electric circuit with only one path through which charge can flow is called a

• A. Parallel circuit
• B. Battery
• C. Series circuit
• D. Switch

Answer: (C)

When there’s only one path for charge to flow, the components must all be connected in a line so the same current passes through each one in sequence. This arrangement is called a series circuit. In a series circuit, the current is the same through every element, and the voltages across the elements add up to the total supply voltage; the total resistance is the sum of the individual resistances. If this single path is broken, the current stops everywhere. A parallel circuit, by contrast, provides multiple paths for current to split between branches. A battery is the energy source, and a switch is just a device that opens or closes the path.
