In an electric circuit, which of the following quantities is equal to the sum of the individual values for all components connected in series?

• A. Total voltage $V$
• B. Total current $I$
• C. Total resistance $R$ in parallel
• D. Total electric charge $Q$

Answer: (A)

Verified step by step guidance

1. Understand the configuration of components in a series circuit: components are connected end-to-end so that the same current flows through each component.
2. Recall that in a series circuit, the current \(I\) is the same through all components, so the total current is not the sum of individual currents but equal to each component's current.
3. Remember that the total voltage \(V_{total}\) across components in series is the sum of the individual voltages across each component, expressed as \(V_{total} = V_1 + V_2 + \dots + V_n\).
4. Note that the total resistance \(R_{total}\) in a series circuit is also the sum of the individual resistances: \(R_{total} = R_1 + R_2 + \dots + R_n\).
5. Understand that electric charge \(Q\) is not additive in this context because charge flow is continuous and the same through all components in series.
