What does parallel wiring increase?

• A. Capacity but not voltage
• B. Voltage but not capacity
• C. Frequency
• D. Inductance

Answer: (A)

Parallel wiring increases the circuit’s capacity to carry current. When conductors are connected in parallel, the total current available is the sum of the currents through each path, so you can handle a higher load without overheating, all at the same supply voltage. The voltage across each branch stays the same as the source, so it does not rise. Frequency is determined by the power source and wiring arrangement doesn’t raise it, and the overall inductance of parallel paths tends to decrease rather than increase. So parallel wiring lifts capacity but not voltage.
