What is the name of A variable resistor with two terminals?
hi, the center terminal (attached to the wiper contact) tied to one of the ends????
What is the name of the device that changes the ratio of a current in voltage?
A transformer. it steps up / down voltage, and steps down / up current.
When a local variable has the same name as a field the local variable's name does this to the field's name?
When a local variable has the same name as a field, it shadows the field's name within its scope. This means that within that scope, any reference to the variable name will refer to the local variable rather than the field. As a result, the field becomes inaccessible directly by that name until the scope of the local variable ends. This can lead to confusion and potential bugs if not managed properly.
Is voltage established through a resistor or across a resistor?
Current = charge (electrons) flowing through a resistor.Voltage = energy lost across a resistor.Power = energy lost across a resistor per second.So yes you are correct. Current is established through a component, while voltage and power are established across a component.Answer'Voltage' is a synonym for 'potential difference'. As the name implies, voltage describes the difference in potential between (or 'across') two different points. So voltage is applied ACROSS a resistor.Further to the original answer. voltage is NOT equivalent to 'the energy lost across a resistor', and power is NOT 'established across a resistor' (power is simply a 'rate', nothing more)!
What is Variable Shadowing in Java?
In Java, there are three kinds of variables: local variables, instance variables, and class variables. Variables have their scopes. Different kinds of variables have different scopes. A variable is shadowed if there is another variable with the same name that is closer in scope. In other words, referring to the variable by name will use the one closest in scope, the one in the outer scope is shadowed.A Local Variable Shadows An Instance VariableInside a class method, when a local variable have the same name as one of the instance variable, the local variable shadows the instance variable inside the method block.
What name is used for a high power variable resistor?
potentiometer
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 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?
hi, the center terminal (attached to the wiper contact) tied to one of the ends????
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.
