In a parallel circuit powered by a 24-volt source, the voltage across each resistor is what relative to the source voltage?

• A. 12 volts
• B. 6 volts
• C. 48 volts
• D. 24 volts

Answer: (D)

In a parallel circuit, all components are connected directly across the same two nodes, so each resistor shares the same voltage as the source. That means the voltage across every resistor is the full source voltage, regardless of how many resistors are in parallel. With a 24-volt source, each resistor experiences 24 volts across it. The current through each resistor can vary (I = V/R for that branch), but the voltage remains the same across all branches. Values like 12 volts or 6 volts would imply voltage sharing as in a series arrangement, which isn’t how parallel circuits behave, and 48 volts would require a source higher than provided or some voltage-boosting element, which isn’t present here.
