What is voltage?
Answer:
Voltage (sometimes also called electric or electrical tension) is the difference of electrical potential between two points of an electrical or electronic circuit, expressed in volts. It measures the potential energy of an electric field to cause an electric current in an electrical conductor. Depending on the difference of electrical potential it is called extra low voltage, low voltage, high voltage or extra high voltage.
potential difference
it causes the charges to flow.
without potential difference, there is no current.
It is the measure of the current of some thing that uses electricity.
A measure of electricity.
Voltage is the difference in electrical potential between two points.
A nice analogy is water pressure. It is this "pressure" that the electrons (or positive "holes") experience and so influences the rate at which they flow over (i.e. the current or amperage) - in the same way that higher water pressure increases the amount of water that flows through a conduit.
Voltage is the difference in electrical potential between two points in a circuit.
It's sometimes compared to water pressure. Voltage is kind of like the pressure in the pipe; Amperage is kind of like the width of the pipe.
A measure of electrical potential.
it is same as potential difference ..
the exact definition u need to know is.....
It is the difference in the potential between the 2 electrodes .
voltage is also termed as P.D or V
here are the formulas u will come across.....
V=IR (ohms law ..v = voltage.I = current,R = resistence)
Q=CV (Q is charge,V is Voltage,C is capacitance)
Voltage (sometimes also called electric or electrical tension) is the difference of electrical potential between two points of an electrical or electronic circuit, expressed in volts ... It measures the potential energy of an electric field to cause an electric current in an electrical conductor. Depending on the difference of electrical potential it is called extra low voltage, low voltage, high voltage or extra high voltage.
Voltage is the driving force for current in a circuit.
Voltage is associated with potential difference between 2 points in an electric field. Its defined as the work needed to be done in moving a point charge in an electric field from one point to other in an electric field opposite to the direction of the field.
Voltage is also electric potential energy per unit charge, measured in joules per coulomb ( = volts). It is often referred to as "electric potential", which then must be distinguished from electric potential energy by noting that the "potential" is a "per-unit-charge" quantity. Like mechanical potential energy, the zero of potential can be chosen at any point, so the difference in voltage is the quantity which is physically meaningful. The difference in voltage measured when moving from point A to point B is equal to the work which would have to be done, per unit charge, against the electric field to move the charge from A to B.
Voltage is a driving FORCE that causes electrons to move.
It is called the EMF (Electro-Motive Force of a circuit).
It is a 'Potential Difference' (P.D.), like a 'Pressure Difference' across a circuit.
The difference of electrical potential between two points of an electrical or electronic circuit, expressed in volts . It measures the potential energy of an electric field to cause an electric current in an electrical conductor. Depending on the difference of electrical potential it is called extra low voltage, low voltage, high voltage or extra high voltage.
Its is the POTENTIAL DIFFERENCE.
