What is the name of a variable resistor with 3 terminals?
It's called a 'variable resistor'. However, it can function as a 'rheostat' (to control current) when two terminals are connected, or as a 'potentiometer' (to control voltage) when three terminals are connected. The terms, 'rheostat' and 'potentiometer' do not describe the device itself, but how it is being used.
What is the function of rheostat in this experiment?
A rheostat is the name given to a variable resistor when it is used to control current. When a variable resistor is used to control voltage, we call it a potentiometer.A rheostat is connected in series with a load, and two of its three terminals are used. A potentiometer is connected in parallel with the supply, and each of its three terminals are used.So the terms 'rheostat' and 'potentiometer' are the names given to describe the function of a variable resistor, not the variable resistor itself.
What type of transducer Is potentiometer?
what type of transducer potentiometer
How do you prevent shock by capacitors?
Discharge the capacitor, normally with a resistor accross the terminals (Calculated size)
What is sensitivity of a potentiometer?
Sensitivity of potentiometer means~ smallest potential difference that can be measured with the help of it.

What is the difference between potentiometer and light-sensitive diode?
potentiometer is not sensitive to lightpotentiometer has three terminals, diode has two
What is another term for potentiometer?
A potentiometer and a rheostat are two different applications for a variable resistor.A potentiometer is a variable resistor, connected (using its three terminals) as a variable potential divider.A rheostat is a variable resistor, connected (using two of its three terminals) to adjust current.
Can a potentiometer be used as a rheostat?
Yes, a potentiometer can be used as a rheostat by only using two of the three terminals. By connecting one end of the resistive element to the wiper terminal, you can adjust the resistance across the other two terminals to control the current flow like a rheostat.
What is the difference between normal resistance and potentiometer?
Resistors are either fixed value, or variable. A variable resistor has three terminals; one at either end and one attached to a moving 'wiper', and can be connected either as a potentiometer or as a rheostat. So 'potentiometers' and a 'rheostats' are different applications for variable resistors. A potentiometer uses all three terminals, and is used to control levels of potential; whereas a rheostat uses just two of the three terminals, and is used to control current.
Where a varying voltage is required this can be achieved by?
Variable resistors are called rheostats. A potentiometer can be used as a rheostat. Use the wiper terminal and one of the outside terminals for connections. The third terminal of the potentiometer is unused.
How many terminals does a variable resistor normally have?
2 terminals. One is connected to the sliding contact. Other is to the coil of wire.
How can a potentiometer be a rheostat?
A rheostat and a potentiometer are two different applications for the same device, a variable resistor. These devices have three terminals. Two terminals are connected across the complete resistor, while the third terminal is connected to a controllable wiper. The variable resistance is provided between the wiper terminal and either one of the other two terminals.When used to control current, it is called a rheostat. When used to control voltage, it is called a potentiometer.
Can you cut one leg of a potentiometer?
Yes, you can cut one leg of a potentiometer, but it will likely render the component non-functional. A potentiometer has three terminals: two are connected to the resistive track, and one is the wiper that adjusts resistance. Cutting one leg disrupts the electrical connections necessary for it to operate properly. If modifications are needed, it's better to use a different component or a new potentiometer.
How many terminals are there in relay?
Relays typically have at least two terminals: one for the input (coil) and another for the output (contacts). However, the total number of terminals can vary depending on the relay type; for example, a simple relay may have four terminals (two for the coil and two for normally open/normally closed contacts), while more complex relays can have additional terminals for multiple circuits or configurations.
What is the symbol of a trim-pot?
The symbol of a trimmer potentiometer (trim-pot) in circuit diagrams typically resembles that of a regular potentiometer but includes an additional line or arrow indicating its adjustable feature. It usually features three terminals: two fixed outer terminals and one adjustable middle terminal. The symbol may also be annotated with "TRIM" or similar labels to specify its function.
How do you wire a dual potentiometer?
To wire a dual potentiometer, first identify the three terminals on each pot: the first terminal is the input (usually connected to the voltage source), the second terminal is the wiper (output), and the third terminal is the ground. Connect the input terminal of both potentiometers to the voltage source. Then, connect the wiper terminals to your output device, and finally, connect the ground terminals to the common ground. Ensure that the wiring matches the desired function, such as volume control or tone adjustment in audio applications.
