13.WHAT IS THE DIFFERENCE BETWEEN A DC MOTOR AND A SERVOMOTOR?

# data[].attributes.body
IMPORTANT DIFFERENCES
First, on the servo motor, all that matters is the absolute duration of the positive-going pulse, which corresponds to a commanded output position of the servo shaft. Second, the servo has its own power electronics, so very little power flows over the control signal. All power is draw from its power lead, which must be simply hooked

# data[].attributes.body
Emits light when a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons.

Is a component of a machine, responsible for moving or controlling a mechanism or system, for example by actuating (opening or closing). It is a mover.

10.WHAT IS THE FUNCTION OF A ULTRASONIC SENSOR?

# data[].attributes.body
It can measure the distance to an object by using sound waves.
measures distance by sending out a sound wave (specific frequency) and listening for that sound wave to bounce back.

Are temperature-sensing elements made of semiconductor material, has been sintered to display large changes in resistance (in proportion to small changes in temperature).

# data[].attributes.body
Is a component that has  a variable/not variable  resistance that changes with the light intensity that falls upon it. This allows them to be used in light sensing circuits.

# data[].attributes.body
Is a device that detects and responds to some type of input from the physical environment.
It could be light, heat, motion, moisture, pressure, or more great number of other environmental phenomena.

Process elements:
The process or plant is the system of which a variable is being controlled.
This produces a signal related to the variable being controlled and provides the signal fed back to the comparison element to determine if there is an error.

# data[].attributes.body
Comparison element:
Compares the reference value with the measured value and produces an error signal.
Control element:
This element decides what action to take when it receives an error signal.
Correction element:
This element is used to produce a change in the process to remove the error and is often called an actuator.

For example the interaction between a heater in a room and the person who controls the heater.
Explanation: the person adjusts the heater to a certain temperature.
The current room temperature provides feedback to the controller.
An other example is an amplifier is put next to a microphone, so the input volume will keep increasing, resulting in a very high output volume.
