When four resistors are connected in parallel and energized by a 24 volt source, what is the voltage drop across each resistor?

In a parallel circuit, all components share the same voltage across their terminals. This is a fundamental property of parallel connections. Therefore, when four resistors are connected in parallel and supplied with a 24 volt source, each resistor experiences the full source voltage.

Since there is no other component that would drop the voltage in the path to the resistors, the voltage drop across each resistor remains equal to the voltage of the source, which is 24 volts in this case. The arrangement of resistors does not affect the voltage; rather, it influences the total current and overall resistance of the circuit.

Understanding this principle is crucial in many applications within avionics and electrical systems, where the behavior of electrical components can significantly impact functionality and safety.
