Question

Explain in brief how to use potentiometer as a voltage divider

Answer 1

Answer:

1.) Begin by bringing power onto the board.

2.) Set up the Voltage Divider. Remember to GROUND the potentiometer.

Forgetting to ground the POT seems to be the common mistake.

3.) Place the LED and current limiting resistor on the board.

Answer 2

Answer:

The potentiometer can be used as a voltage divider to continuously change the output voltage of a voltage supply

Explanation:

• A three-terminal resistor with a sliding or revolving contact is known as a potentiometer.
• It is a voltage divider with two static contacts and one movable contact that may be adjusted.
• A wiper moves across the resistance element, commonly in an arc regulated by a rotary knob, as the moving terminal.
• Rotating the knob divides the voltage across the resistance element in a ratiometric manner.
• When using a potentiometer as a variable voltage divider, connect one contact to the input voltage, the middle contact to the output voltage, and the other contact to the ground.
• When the potentiometer's rotating or sliding handle is turned on, the moveable contact glides on the resistor.
• At this time, an output voltage is related to the external voltage, wiper angle, and travel stroke.
• Potentiometers are commonly used to adjust the volume in speakers and receivers. Furthermore, because of its insufficient power, it is unable to operate the motor directly.
