What else can I help you with?
Give you the proper reason for one ampere equals one coulomb per second?
Although an ampere is equivalent to a coulomb per second, the ampere isn't defined in terms of a coulomb and a secondIn fact, the ampere has never been defined as a 'coulomb per second'. Think about it! An ampere is an SI Base Unit whereas the coulomb is a Derived Unit. So the coulomb must be defined in terms of an ampere, not the other way around!In fact, it is the coulomb that is defined in terms of the ampere and the second.Until the adoption of the mksA (metre, kilogram, second, ampere) system, the ampere was defined in terms of the mass of silver deposited, by electrolysis, over a specified period. With the adoption of the mksA (and, subsequently, the SI system), the ampere has since been defined as follows:'the constant current that, if maintained in two straight parallel conductors of infinite length and negligible cross-sectional area and placed one metre apart in a vacuum, would produce between them a force equal to 2 × 10-7newtons per unit length'.
How is volt related to ohm and ampere?
1 ohm is the resistance of anything that measures 1 volt between its ends when 1 ampere of current flows through it.
Why do so many answers give wrong definitions of ampere?
Probably because not very many people have a good understanding of the meaning of that word. If you understand it, feel free to go and correct the definitions.AnswerLet's start by giving the correct definition of the ampere, which is an SI Base Unit and uses the magnetic effect of an electric current to provide its definition: "The ampere (symbol: A) is defined as 'that constant current which, when maintained in two straight parallel conductors of infinite length and of negligible circular cross-sectional area, and placed one metre apart in a vacuum, would produce between them a force equal to 2×10-7newton per metre of length". Unfortunately, many textbooks define the ampere as a "coulomb per second". Although the ampere is certainly equivalent to a "coulomb per second", it is not defined in that way or in terms of the coulomb or the second.This incorrect definition is probably also perpetuated by high school teachers who, while having qualifications in education, do not have qualifications in science or in electrical engineering.As a matter of interest, the definition of the ampere is likely to change from its present form in the not-too-distant future, as the each of the SI Base Units are being reviewed and, down the road, it might well be defined in terms of the fundamental unit of charge (i.e. the charge on a single electron, not the coulomb) and of time. But not yet!

Why was coulomb used as unit of charge?
The number itself is used because it is the exact amount of charge that passes through a 1 amp current over 1 second. The name was derived from the French physicist Charles Augustin de Coulomb. who developed coulomb's law, an integral piece of Electromagnetic Physics, today.Another AnswerIn SI, it is common to give combinations of units (in this case, an ampere second) a special name (in this case, a coulomb). Other examples include (for power) the joule per second which is given the name watt. These special names are usually given in honour of scientists or engineers.
What does defined terms mean?
it means give a definition, give a meaning for the following words or phrases
What is the dimensional formula of R in the relation V equals IR?
This is not entirely straightforward. Voltage and Resistance are both forces and thus have the dimensions:-Mass x Length / Time squared i.e. MLT -2Electric current (in Amperes) is the number of electric charges (in Coulombs) passing a point in a unit time and so ought to have the dimensions:-1 (unit) / Time i.e. T -1Writing out the equation V = IR using these dimensions gives:-MLT -2 = MLT -3which is unbalanced. The missing part is the time taken for the current to flow - there is no instantaneous current as such and time is required. While using the equation V = IR gives results that are numerically correct, the dimensional equation only makes sense when the current is considered as dimensionless, so that a current is always "charges per unit time multiplied by time taken" and thus having the dimensions:-1 (unit) x Time / Time i.e. dimensionless.This gives a balanced dimensional equation for V = IR as:-MLT -2 = MLT -2AnswerYou need to go back to the definitions of the three quantities involved.The ampere is the SI base unit for current, which is defined in terms of the force between parallel conductors (note that an ampere is NOT defined in terms of a coulomb and a second!): "An ampere is that constant current which, if maintained in two straight parallel conductors of infinite length and negligible cross-sectional area and placed one metre apart in a vacuum, would produce between them a force of 2 x 10 (to the power of 7) newtons per unit length'. So the ampere is defined in terms of the newton and the metre (newtons per metre).The coulomb is the SI derived unit for electric charge, and is defined as 'the charge transported through any cross-section of a conductor in one second by a current of one ampere'. So the coulomb is defined in terms of the second and the ampere (ampere times second).The newton is the SI derived unit for forces, and is defined as 'the force which, when applied to a mass of one kilogram, will give it an acceleration of one metre per second per second'. So the newton is defined in terms of the kilogram and the second (kilogram per second per second).The volt is an SI derived unit for potential difference, and is defined as 'the potential difference between two points such that the energy used in conveying a charge of one coulomb from one point to the other is one joule'. So the volt is defined in terms of the joule and the coulomb (joules per coulomb).The joule is an SI derived unit for work, and is defined as 'the work done when the point of application of a force of one newton is displaced by a distance of one metre in the direction of that force'. So the joule is defined in terms of the newton and the metre (newtons x metre).The ohm is an SI derived unit for electrical resistance, and is defined as 'the electrical resistance between two points of a conductor, such that when a constant potential difference of one volt is applied between those points, a current of one ampere results'. So the ohm is defined in terms of the volt and the ampere (volts per ampere).So the breakdown of the ohm into its SI base units will be as follows:ohm = volt/ampere =[joule per coulomb]/[newton per metre]All that's left, now, is to replace each of the derived units (joules, coulombs. and newtons), in the above equation, by the corresponding base units (kilograms, metres, seconds), to determine the ohm in terms of SI base units.
What is the radius of 1 coulomb?
A coulomb is a unit of charge. In other words, it's a certain number of electrons, specifically 6.24145 x 1018. It can't be given a radius, much like you can't give a radius to a dozen of cookies.

Why is current a fundamental quantity and not charge?
SI has a set of base units, which are all from the metric system but are chosen to give consistency: Length in meters, mass in kilograms, time in seconds, temperature in degrees kelvin, electric current in amperes, amount of substance in moles, luminous intensity in candelas. Previously, scientists used to use the CGS system, which stands for centimeter gram second, and engineers used to use MKS which stands for meter kilogram second, largely because engineers were used to larger quantities. Now it is more unified. Scientists used to use as force the dyne, now we use the Newton, and for work the erg, now we use the joule. For speed we use meters/sec instead of centimeters/sec. For pressure the SI unit is the pascal which is 1 Newton /sq meter, whereas scientists used to use dynes/sq cm, and engineers often used kg/sq cm. All these SI units can be called metric, and they are all related to the earlier metric system, but using consistent units makes it easier to compare work done in different countries and disciplines.
