The total voltage applied to a voltage divider is equal to the?

• A. Load's voltages only
• B. Sum of the input and load voltage
• C. Sum of the voltages across the divider
• D. Input voltage minus the load's voltages

Answer: (C)

In a voltage divider, the total voltage applied is the sum of the voltages across each resistor in the divider. This is due to the principle of voltage division, where the input voltage is divided among the resistors based on their resistance values. Each resistor in the divider has a certain voltage drop, and when these drops are added together, they equal the total applied input voltage. Therefore, the correct understanding is that the total voltage applied corresponds directly to the sum of the individual voltages across each segment of the voltage divider. This is consistent with Kirchhoff’s voltage law, which states that the total voltage around a closed loop in a circuit must equal zero. Thus, it captures the fundamental operation of the voltage divider effectively.
