In a series circuit, voltage is described as being what?

• A. Constant
• B. Cumulative
• C. Minimal
• D. Variable

Answer: (B)

In a series circuit, the voltage is described as cumulative. This means that the total voltage across the entire circuit is the sum of the voltages across each individual component. For example, if there are three resistors in series, and the voltage drop across each resistor is measured, the total voltage provided by the power source must equal the sum of those individual voltage drops. This cumulative characteristic results from the principle of conservation of energy; the total energy supplied by the power source is distributed among all the components connected in series. Thus, in series circuits, understanding that voltage accumulates gives valuable insight into how to analyze circuit behavior and design.
