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.
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 man terminals does a variable resistor normally have?
Definitely two. Possibly three.
