In a parallel circuit with four 6-ohm resistors across a 24-volt battery, what is the voltage across resistor-three (VR3)?

In a parallel circuit with four 6-ohm resistors across a 24-volt battery, what is the voltage across resistor-three (VR3)?

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

Answer: (B)

In a parallel circuit, all components connected across the same two points share the same voltage, equal to the source. Since those four 6-ohm resistors are directly across a 24-volt battery, each resistor—including resistor three—has 24 volts across it. The current through each resistor would be 24 V divided by 6 Ω, which is 4 A, so the total current from the source is 16 A. The other values would require different configurations (like a voltage divider or no potential difference), which isn’t the case in a parallel setup.
