When we want to regulate somthing ;we use variable resistors for example :volume control in radios and volume in headset. Also , the variable resistors can forms a potential devider in which the overall resistance between the two end points remain the same,but the ratio of the two resistors in the legs changes.so the variable resistor is affectively a potential divider.
Also, the variable resistor can forms a potential divider in which the overall resistance between the two end points remains the same, but the ratio of the two resistors in the legs changes. So, the variable resistor is effectively a potential divider.
these are specially made components made to provide resistance, they control how much current flows in a circuit.
It can be used to control the amount of current flowing through the circuit.
If you have a light switch where you can brightener it or dim it that is a VARIABLE RESISTOR.
Variable resistor. The value of the variable resistor can be changed at any given moment.
A potentiometer.
Typically, yes.
It is a resistor which resistance is changeable, such as a potentiometer.
Potentiators works well as a voltage resistor or variable resistor. It is often used for volume controls on a radio, but they can be cumbersome.
how do test a variable resistor
how connect a variable resistor to circuit
If you have a light switch where you can brightener it or dim it that is a VARIABLE RESISTOR.
A variable resistor means that the resistance can be varied, usually by using a slide. A fixed resistor can not be varied.
yes, a variable resistor
Variable resistor is an resistor that can change its resistance manually, by rotating a handle or a screw.
its the colour of the fixed and the variable we define it by its power and name
The volume knob on an audio device (radio, TV) is an example of a variable resistor. A variable resistor is also known as a potentiometer.
