In a parallel circuit, does the voltage across each resistor equal the supply voltage?

In a parallel circuit, all components are connected directly across the same two points of the power source, so they share the same potential difference. That means the voltage across each resistor equals the supply voltage, even though the currents through each resistor can be different depending on their resistance. The total current is the sum of the branch currents, but the voltage stays the same across every branch. In ideal circuits, no extra drops occur in the wiring, so the voltage across each branch matches the supply voltage.
