A voltage gradient or, more accurately, potential gradient, is the change in electric potential measured between a point of high potential and a point of low potential. It is normally measured with respect to one or other of these two points.
A practical example of a potential gradient can be demonstrated by connecting a variable resistor as a potentiometer. If an external voltage is applied across opposite ends of the potentiometer, then a potential gradient can be observed by connecting a voltmeter between one end of the potentiometer and its wiper terminal, and varying the position of the wiper. As the wiper is moved from one end of the potentiometer to the other, the potential will be seen to fall towards zero.

Is a UJT a voltage controlled or current controlled device?
voltageCurrent between the two bases of the UJT sets up a voltage gradient in the semiconductor. When the voltage on the emitter of the UJT rises high enough to forward bias the emitter-base junction at the voltage of the interbase gradient where the emitter is located, the UJT "turns on".
Define rated impulse voltage?
Simply, the voltage which is withstand by the test object as an impulse is called as rated impulse voltage.
Define rms reverse voltage of a diode?
A DIODE will breakdown at a certain reverse voltage if RMS VOLTAGE IS SPECIFIED THEN the actual voltage will be RMS volts times 1.41
Why are the equipotential lines near conductor surfaces parallel to the surface?
For conductors, the electric field perpendicular to its surface and no field exist within the conductor. As a result the equipotential lines are found near the surface. They are parallel to the surface since equipotential are perpendicular to field lines.
What is considerede low voltage?
Low voltage is a relative term, as there is no 'level' at which a voltage is rated 'low'. Electrical safety codes define low voltage as circuits that do not require the same protections necessary at higher voltages.
What is valtage gradient?
Probably an incorrect spelling of voltage gradient.
How does voltage gradient affect separation of charged particles in an electric field?
There is a direct relationship between the voltage gradient of an electric field and the separation of the charges. Higher voltage gradients will separate charges farther.
What is the physical significance of gradient define?
The gradient of a curve is the rate of change in the dependent variable relative to the independent variable.
Define the puncture voltage?

Is a UJT a voltage controlled or current controlled device?

How you can reduce voltage of a transformer?
Number of turns in the secondary winding define the voltage. Change the number of turn to change the voltage.
Define rated impulse voltage?
Simply, the voltage which is withstand by the test object as an impulse is called as rated impulse voltage.

Define rms reverse voltage of a diode?
A DIODE will breakdown at a certain reverse voltage if RMS VOLTAGE IS SPECIFIED THEN the actual voltage will be RMS volts times 1.41
Define term gradient give definition of fick's law?
Fick's laws of diffusion describe diffusion and can be used to solve for the diffusion, the concentration gradient (spatial derivative), or in simplistic terms the concept.
What is the driving force of the membrane?
The driving force is explained by two factors: voltage gradient and concentration gradient. When there are more ions inside of a cell than outside of a cell, the concentration gradient is pushing the ion to exit the cell. This is simple diffusion. If that ion carries a negative charge then it also wants to exit the cell because the outside environment is slightly more positive.So if you add both voltage gradient and concentration gradient you get the driving force. In the example above both gradients are pushing the ion outside of the cell. Sometimes you can have the gradients going in opposites and then the driving force will be determined on which gradient is stronger.
Define the term regulation as applied to dc power supply?
change in load voltage or output voltage changes in load current
