Which statement describes the series circuit rule about current through components?

• A. Law for Current in a series circuit
• B. Law for resistance in a series circuit
• C. Law for voltage in a series circuit
• D. Law for voltage in a parallel circuit

Answer: (A)

In a series circuit, the current remains the same through every component because there is only a single path for current to follow. Charge that flows into the loop must flow out the same amount, so the current does not split or change as it passes through each element. This behavior is described by the law for current in a series circuit. Remember that in a series setup the total resistance adds up and the voltage is shared among the components, whereas the other statements either talk about voltage in a series or current/voltage behavior in parallel configurations, which isn’t what this rule addresses.
