In a parallel circuit powered by 24 volts, the voltage across each resistor is equal to the source voltage.

In a parallel circuit powered by 24 volts, the voltage across each resistor is equal to the source voltage.

• A. 24 volts
• B. 12 volts
• C. 6 volts
• D. 0 volts

Answer: (A)

In a parallel circuit, every component is connected directly across the power source, so the voltage across each branch equals the source voltage. Here, the supply is 24 volts, so each resistor has 24 volts across it, no matter its resistance. The current through each branch may differ (I = V/R for each resistor), but the voltage across every resistor remains the same as the source. The other numbers would only occur if there were a voltage divider or a short, not in a simple parallel setup with an ideal 24 V source. So the voltage across each resistor is 24 volts.
