In a series circuit, there is only one path for current to flow.

• A. There are multiple paths
• B. There is only one path for the current to flow
• C. Current splits equally across components
• D. Path depends on voltage

Answer: (A)

In a series circuit, the current has only one path to flow through. Because there’s no branching, the same current travels through every component in sequence. The total resistance is the sum of the individual resistances, so the current is determined by I = V_total / (R1 + R2 + …). The voltage across each component adds up to the source voltage, with each drop equal to I times its resistance (Vi = I Ri). If the path is interrupted anywhere, all current stops. This single-path behavior is what defines a series connection, setting it apart from parallel circuits where current can split among multiple paths.
