What is the definition of electric bulb?
A glass sphere containing a metal element that glows when electricity is applied.
How do you define voltage gradient?
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.
Definition of electric force?
The terminology used in the electrical field is EMF. It is Electro Motive Force, in other words voltage.
What is definition of electric current?
Current is the motion of electrons in a conductor being propelled by electromotive force (voltage).
Why electric field is negative gradient of electric potential?
The electric field is the negative gradient of the electric potential because it points in the direction of steepest decrease in potential. This relationship is based on the definition of potential energy as work done per unit charge. Negative gradient signifies the direction of decreasing potential with respect to position in space.
What is one way to make conduction?
First the conductor should be available (as copper, aluminum, iron, ... ) then to have a gradient (electric gradient, temperature gradient, ...)
What is the relationship between the electric field and electric potential in a given region of space?
The electric field and electric potential in a given region of space are related by the equation E -V, where E is the electric field, V is the electric potential, and is the gradient operator. This means that the electric field is the negative gradient of the electric potential. In simpler terms, the electric field points in the direction of the steepest decrease in electric potential.
What is the correct definition of stream gradient?
A stream gradient is the grade measure by the ratio of drop in elevation of a stream. It is expressed as feet per mile.
What is the relationship between the electric field equation and voltage in an electric field?
The electric field equation describes the strength and direction of the electric field at a point in space. Voltage, on the other hand, is a measure of the electric potential difference between two points in an electric field. The relationship between the electric field equation and voltage is that the electric field is related to the gradient of the voltage. In other words, the electric field is the negative gradient of the voltage.
What is the relationship between the scalar potential and the electric field in a given region of space?
In a given region of space, the scalar potential is related to the electric field by the gradient of the scalar potential. The electric field is the negative gradient of the scalar potential. This means that the electric field points in the direction of the steepest decrease in the scalar potential.
What is the definition of electric current the the units of electric current?
ampere
Is potential gradient vector or scalar?
The potential gradient is a vector quantity. It represents the rate of change of the scalar electric potential with respect to position in space.
What is the definition of ground gradient?
According to the IFSTA Essentials of Firefighting 5th Edition, a ground gradient is Produced by an electrical current passing from a downed power line through the ground along the path of least resistance.
Why are all horizontal lines parallel?
By definition, lines are parallel if they have the same gradient (slope). Any horizontal line has a gradient of 0, so it is parallel to any other horizontal line.
Do electrons move up or down a potential gradient?
The potential gradient gives the electric field intensity E at point in electric field which is directed from high to low potential. An electron being a negative charge particle therefore will tend to move from low potential to high potential, hence will move up the electric field
What is the definition for electric current?
Flow of electrons
