What happens to voltage across each resistor in a parallel circuit?

In a parallel circuit, the voltage across each resistor is the same. This uniformity occurs because all resistors are connected directly across the same two points in the circuit, sharing the same potential difference. According to Ohm's law (V = IR), while the current flowing through each resistor may differ based on its resistance, the voltage remains constant across all resistors in parallel. This fundamental characteristic is crucial in understanding parallel circuits: regardless of the resistor values, the voltage drop across each one is equal to the source voltage. This principle facilitates the design of circuits, ensuring that devices can operate independently of one another while receiving the same voltage.
