What is the most common type of load bank?

• A. Reactive
• B. Capacitive
• C. Resistive
• D. Inductive

Answer: (C)

The most common load bank is resistive because it provides a straightforward, real-power load that converts electrical energy into heat with essentially unity power factor. This makes testing generators simple, predictable, and repeatable: you get known kilowatts without introducing reactive components that would shift the phase and complicate measurements. Resistive banks are also inexpensive, reliable, and easy to scale by adding or removing resistor elements to match the test needs. Inductive or capacitive banks introduce reactive power and phase shifts, which isn’t ideal for standard generator tests and is used only for specialized scenarios like simulating motors or studying power-factor correction.
