Is it true or false that the total voltage drops in a series circuit equals the supplied voltage?

• A. True
• B. False
• C. Depends on the circuit
• D. Only for resistive loads

Answer: (A)

In a series circuit, the total voltage drop across all components is indeed equal to the supplied voltage. This principle is derived from Kirchhoff's Voltage Law, which states that the sum of the electrical potential differences (voltage) around any closed loop in a circuit must equal zero. When components such as resistors are connected in series, the voltage supplied by the source is divided among the components according to their resistances. The total of these individual voltage drops will add up to the total voltage of the source, ensuring that energy is conserved within the circuit. Each component consumes a portion of the energy provided by the power source, leading to the total sum of voltage drops equating to the source voltage. This relationship holds true irrespective of the type of components used, as long as they are connected in series and the circuit is complete, meaning that there are no breaks in the path for current flow. Consequently, when analyzing series circuits, one can confidently rely on the fact that the total voltage drop will match the supplied voltage.
