An electrical device that resists the flow of electrical current.

• capacitor
• diode
• resistor
• transistor

An electrical device used to store electrical charge.

• diode
• resistor
• transistor
• capacitor

A type of motor that can be directed to turn to face a specific direction, rather than just spin forward or backward.

• fan
• servomotor
• robotic arm
• capacitor

A device that responds to a physical stimulus (as heat, light, sound, pressure, magnetism, or a particular motion) and transmits a resulting impulse (as for measurement or operating a control).
