Which term describes a circuit where resistors are arranged in a single path?

• A. Series Circuit
• B. Parallel Circuit
• C. Open Circuit
• D. Short Circuit

Answer: (A)

This question tests understanding of how current flows when components are arranged in a single path. In a series circuit, resistors are connected end-to-end so there is only one path for current. The same current passes through every component, one after another. The total resistance is the sum of the individual resistances, so adding more resistors increases the overall resistance and lowers the current for a given supply voltage. The voltage across the resistors adds up to the total supply voltage, with larger resistances taking larger shares of the voltage. If any part of the path is interrupted, the circuit becomes open and current stops. This is what sets series circuits apart from parallel circuits, which have multiple paths for current; an open circuit means no complete path, and a short circuit means a very low-resistance path that bypasses the intended load. So when resistors are arranged in a single path, the term that describes that arrangement is a series circuit.
