What is the circuit diagram of MOSFET as a variable resistor?
It is here at this website. www.mosfetdiagrams.co.uk/varibles
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.
Why resistor should disconnected from the circuit when measured the value of resistor?
if not disconnected you will measure the resistance of the circuit in parallel with the resistor.
What is the advantages of variable resistor?
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.
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.
How connect a variable resistor to circuit?
To connect a variable resistor to a circuit, identify the two terminals of the variable resistor. Connect one terminal to the input or output of the circuit where you want to adjust the resistance. Connect the other terminal to either the ground or another reference point depending on the circuit's design. Ensure that the resistance value on the variable resistor is adjusted as needed for your circuit application.
What does a variable resistor diagram illustrate?
A variable resistor diagram illustrates how a resistor can change its resistance value, allowing for adjustable control of electrical current in a circuit.
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 are the independent dependent and control variables in series circuit containing 1ammeter a resistor a light bilulb and 3cells?
Independent variable: the number of cells in the circuit. Dependent variable: the current measured by the ammeter. Control variable: resistance of the resistor, type of light bulb.
What scientific term is used to describe the arrangement of a variable resistor and the diode which connect in a series circuit?
There isn't anything "scientific" about this simple series circuit. If you've got a variable resistor (a potentiometer) and a diode in series, you have a simple series circuit with the two components in it.

Is it possible to apply voltmeter across a variable resistor?
Of course. A good voltmeter can be applied across anything, since its impedance is high and its presence has no effect on the operation of the circuit. When it's connected across a variable resistor, the voltmeter most likely reveals a changing voltage as the resistor is varied.
What are the common defects of a variable resistor?
Normally if a resistor fails they will either increase in value or open up at all (open circuit).
What products use Variable resistor?
Toasters and lightbulbs.AnswerA resistor is an circuit component. So, while toasters and light bulbs have resistance, they are not resistors!
How can a variable resistor be used to control the brightness of light?
A variable resistor can be connected in series with a light bulb in a circuit. By adjusting the resistance of the variable resistor, the current flowing through the circuit changes, affecting the brightness of the light bulb. Increasing the resistance decreases the current, resulting in lower brightness, while decreasing the resistance increases the current, leading to higher brightness.
When you turn the knob of your radio to tune to a station what do you chang?
You change a variable resistor in the the tuning circuit. The value of the resistor dictates the frequency that the radio is receiving.
