What is another name for a rheostat?

A variable resistor is another name for a rheostat.


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 is other name for variable ressitance?

Another name for variable resistance is potentiometer. It is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider.


What is another name for a variable resistor?

If the two of the three terminals on a Potentiometer are used, then it may be used as a variable resistor.AnswerA variable resistor may function as a potentiometer (using three terminals) or as a rheostat (using two terminals). Its correct name is 'variable resistor', while the terms 'potentiometer' or 'rheostat' describe how it is being used.


What is the name of A variable resistor with two terminals?

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 a variable to the second power called?

A variable raised to the second power would be refered to as "squared." Some math-based programs like Excel let you enter a power with a carot, ie, "(variable name)^2" if you want to calculate the answer.


What is the name for a polynomial equation containing a variable to the second power?

A quadratic equation.


What is the name of the electrical part that is used to change the amount of current that flows to a heater motor?

A resistor resists the flow of current in a circuit but a transistor changes the amount of current through a device. This is called current magnification. Field effect transistors FETs and MOSFETs (metal oxide semiconductor field effect transistor) may also change the amount of current to a load lastly a variable resistor or a potentiometer or a variable resistor can variate the amount of current at your will


What is the other name for rheostat?

The other name for a rheostat is a variable resistor. It is used to control current flow in a circuit by adjusting its resistance. Rheostats are often employed in applications such as dimming lights or controlling the speed of motors.
