The sum of the power absorbed by all loads in a voltage divider equals the?

• A. Total power supplied by the source
• B. Total power absorbed by the first load
• C. Resistance of the loads within the voltage divider
• D. Power absorbed across any load within the voltage divider

Answer: (A)

In a voltage divider circuit, the total power absorbed by all loads is equal to the total power supplied by the source. This principle is based on the conservation of energy, where the power supplied must equal the power absorbed by the loads connected across the voltage divider.

When the source voltage is applied, it causes current to flow through the resistors (or loads) arranged in the voltage divider, resulting in power being dissipated as heat or used by the loads. The total power supplied by the source is distributed among all the loads according to their resistances and the voltage drop across them. This means that the sum of the individual power absorbed by each load will equal the power provided by the voltage source.

This relationship is fundamental in circuit analysis and helps ensure proper functioning and efficiency within electronic circuitry. It also underscores the importance of correctly calculating and predicting voltage and current values when designing circuits and analyzing load behavior.
