What is the result of adding a third resistor in parallel with two others regarding total voltage drop?

In a parallel circuit, the voltage across each resistor remains the same as the total voltage supplied by the source. This means that regardless of how many resistors are added in parallel, the voltage drop across each resistor does not change. Therefore, when a third resistor is added in parallel with two others, the total voltage drop across the entire circuit remains equal to the voltage of the power source.

The resistors in parallel provide multiple pathways for current to flow, but they do not affect the voltage drop experienced by each branch of the circuit. This is a fundamental characteristic of parallel circuits—while adding additional resistors can change the total current and the overall resistance of the circuit, the voltage across all branches remains constant. Thus, the result of adding a third resistor in parallel with two others regarding the total voltage drop is that it remains the same as that of the power source.
