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.
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?
whta is puncture voltage
Is a UJT a voltage controlled or current controlled device?

How does voltage gradient affect separation of charged particles in an electric field?
The voltage gradient directly impacts the force experienced by charged particles in an electric field. Higher voltage gradients result in stronger forces, leading to faster separation of charged particles in the field. This can be utilized in techniques like electrophoresis for separating molecules based on their charge and size.
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?
Gradient refers to the rate of change of a variable over a specific distance or direction. Fick's Law is a mathematical equation that describes the flux of a substance through a medium, considering the concentration gradient of the substance and the permeability of the medium. It is commonly used in fields like chemistry and biology to determine the rate of diffusion of molecules.
What is the driving force of the membrane?
The driving force of the membrane is the concentration gradient of molecules or ions across the membrane. This gradient creates a potential difference that can drive the movement of substances across the membrane through processes like diffusion or active transport.
Define the term regulation as applied to dc power supply?
change in load voltage or output voltage changes in load current
