What is the squaring effect when doubling the voltage?

• A. The load that can be supplied over the same distance is doubled
• B. The load that can be supplied over the same distance is quadrupled
• C. The load does not change
• D. The load becomes half over the same distance

Answer: (B)

When the voltage is doubled in a power distribution system, the squaring effect refers to how power (which is proportional to the square of the voltage) is affected. Power can be expressed with the formula \( P = V^2 / R \), where \( P \) is power, \( V \) is voltage, and \( R \) is resistance. By doubling the voltage, you effectively increase the power potential by a factor of four, because power is proportional to the square of the voltage. Therefore, if the load is originally capable of being supplied at a certain voltage, increasing that voltage means you can supply much more power across the same resistance. This increase allows the system to supply a load that is quadrupled, hence capturing the essence of the squaring effect. Understanding this principle is crucial for electrical engineers and apprentices, as it guides decisions related to system design, capacity planning, and load analysis in power distribution.
