Engineers and technicians strive for 100% efficiency to use less __________ and generate less heat.

Engineers and technicians strive for 100% efficiency to use less __________ and generate less heat.

• A. Voltage
• B. Power
• C. Energy
• D. Torque

Answer: (C)

Efficiency is about turning input energy into useful work with as little loss as possible. If a system could reach 100% efficiency, all the energy put in would become useful work, leaving no energy wasted as heat. That’s why engineers strive to use less energy to perform the same task, which also reduces heat generation from losses like friction and resistance. The word that fits best is energy, because the goal is minimizing energy use and the associated heat. Voltage is just the driving potential, power is the rate of energy use, and torque is a rotational force, none of which directly capture the idea of reducing energy waste and heat.
