Answer 1

Answer #1

A servomotor uses feedback control mechanism to control its position ,So a servomotor is a closed loop system.

A seromotor has a motor, a sensor and electronics to control its movement.

A servomotor is controlled by sending a PWM (pulse width modulates signal) to its wires. Width of PWM signal decides its position.

So from the given option the incorrect option is C because a servomotor is a closed loop sytem. Option D is also incorrect because it has variable control signal which is PWM signal. Option A is also incorrect. The correct option is option B.
