Which term is associated with the Electrical knowledge category?

• A. Torque wrench
• B. Potentiometer
• C. Gear ratio
• D. Hydraulic actuator

Answer: (B)

Recognize which items are electrical components versus tools or fluid-power devices. A potentiometer is an electronic component that acts as a variable resistor to control or sense electrical signals, such as measuring position or adjusting voltage in a circuit. A torque wrench is a mechanical tool used to tighten fasteners to a specific torque. A gear ratio describes how gear sizes affect speed and torque in a mechanical drive. A hydraulic actuator uses fluid pressure to create motion, which is non-electrical. So the term associated with the Electrical knowledge category is the potentiometer because it directly relates to electrical signaling and control.
