Linear Potentiometer Circuit Diagram. Turn it the other direction and the resistance decreases. Use of voltmeter over ammeter to verify a continuous circuit.
As the symbol suggests a potentiometer is nothing but a resistor with one variable end. These potentiometers are available in different shapes and include three leads. The voltage supply is connected across terminals 1 and 3 positive lead to terminal one while negative lead to terminal three.
Use of voltmeter over ammeter to verify a continuous circuit.
5 - - n. The above image shows a simple circuit to dim an LED. Turn the shaft of the potentiometer one direction and the resistance increases. Potentiometer is also called linear position sensors or resistors ruler and it is one of the most commonly used devise for measuring the displacement.
