Does a variable resistor have a bias?
A variable resistor means that the resistance can be varied, usually by using a slide. A fixed resistor can not be varied.
How do you bias a 2N5777 photo-transistor?
connect the base of the transistor to a variable resistor and to a normal resistor
What is the function of a variable resister in an electrical circuit?
A variable resistor usually has three terminals, one of which is connected to the 'wiper' by which means its resistance is measured. By using all three terminals, we can control the potential difference in a circuit. When used in this way, we call the variable resistor a 'potentiometer'. By using two of the three terminals, one of which must be connected to the variable wiper, we can control the current passing through circuit. When used in this way, we call the variable resistor a 'rheostat'.
What is the name used for a high power variable resistor?
Rheostat
How to calculate the resistance to step down DC voltage?
Connect a variable resistance across DC source (fixed ends of variable resistor or Rheostat) and take decreased DC output across its one fixed terminal and other variable terminal of variable resistor. Other method is connect variable resistor in series with DC output and load, vary the resistance and take decreased DC voltage as required.

Where is a variable resistor in your home?
If you have a light switch where you can brightener it or dim it that is a VARIABLE RESISTOR.
Does a variable resistor have a bias?
A variable resistor means that the resistance can be varied, usually by using a slide. A fixed resistor can not be varied.
Is Light dependent resistor an example of resistor?
yes, a variable resistor
Function of a variable resistor?
Variable resistor is an resistor that can change its resistance manually, by rotating a handle or a screw.
What is the difference between a fixed resistor and a variable resistor?
its the colour of the fixed and the variable we define it by its power and name
What is a variable resister?
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.

What is a resistor whose value can varied over a range of value called?
Variable resistor. The value of the variable resistor can be changed at any given moment.
Are transistor the same as the variable resistor?
no
Difference between variable and fixed resistor?
Variable resistors means that a resistor which can change its resistance by control by any person or it self and fixed resistor means that it can not change its value.
