Which property is true for all resistors in a parallel circuit?

• A. Their voltage is the same
• B. Their current is the same
• C. They all have the same resistance value
• D. They must be active components

Answer: (A)

In a parallel circuit, one key property is that all components are connected across the same two nodes, meaning that they experience the same voltage across them. This characteristic arises from the way parallel circuits work; when multiple resistors are connected in parallel, they share the same voltage supply, which is equal to the voltage across each individual resistor. The common voltage ensures that regardless of the resistance values, the potential difference across each resistor remains unchanged. This relationship is grounded in the fundamentals of electrical circuits, which dictate that in a parallel arrangement, the voltage drop across each component must be equal to the source voltage. While the total current in the circuit may vary among the resistors, as it divides based on their resistances (Ohm's Law), the voltage remains constant across each resistor. This is why the statement regarding their uniform voltage is the correct property for resistors placed in parallel.
