In a load bank, which component is designed to heat by electrical resistance?

• A. Passive Heat Sink
• B. Transformer
• C. Capacitor Bank
• D. Resistive Element

Answer: (D)

The key idea is converting electrical energy into heat on purpose. A load bank is meant to absorb electrical power and dissipate it as heat so the generator or source under test sees a real, resistive load. The component that does this heat generation directly is the resistive element. When current flows through a resistance, power is converted to heat according to P = I^2R (or P = V^2/R). That makes the resistive element the designed heat source in a load bank. The other components aren’t intended to act as the primary heat-producing load. A passive heat sink is there to remove heat from components, not to generate it. A transformer changes voltage and current and does incur some core and copper losses, but its purpose isn’t to produce heat as the main function. A capacitor bank stores energy and can affect voltage regulation; it isn’t designed to dissipate energy as heat in normal operation. So, the resistive element is the component designed to heat by electrical resistance.
