Why is Andre Ampere famous for?
Have you heard of an Ampere? Possibly not, but you likely have heard of the abbreviation, Amp (which is a unit of electric current). Andre Ampere studied current carrying wires and made some important advances in the study of electromagnetism. The unit of current was therefore named in his honour.
Why ampere considered as a fundamental unit though it is a derived one?
Because you have to start somewhere - you can't derive ALL units. You have to have SOME fundamental units.For example, 1 ampere = 1 coulomb / second. That also means that 1 coulomb = 1 ampere x 1 second, or that 1 second = 1 coulomb / 1 ampere. In other words, you can derive any of the three units from the other two. In practice, for base units, units were chosen that can be measured with great precision.Another AnswerThe ampere is not a 'fundamental' unit; it is a base unit. The ampere was chosen as a base unit, because it relates electrical units to mechanical units, being defined, as it is, in terms of the force (which itself is defined in terms of base units) between current-carrying conductors.You might be getting confused because, quite wrongly, the ampere is often defined as a 'coulomb per second'. While it is certainly equivalent to a coulomb per second, it is not definedin this way.
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.
How much strength does an ordinary magnet have?
The problem is that these things are measured in units you've probably never even heard of before. The most powerful superconducting magnets have field strengths of perhaps 20 T (tesla) or so, while a typical refrigerator magnet might be more like 5 mT. And that almost certainly leaves you just as clueless as you were before. A tesla is a kilogram per ampere per second per second, which most likely still doesn't help. It doesn't really help me, at least... I know, intellectually, what a tesla is, and I have some frame of reference (I used to work with a 4.7 T magnet all the time), but "kilogram per ampere per second per second" is not something I can easily picture in my mind. "Webers per square meter" (also equivalent to tesla) is a little better... if you can wrap your mind around what a weber is (a volt-second).
What is the full form of KVA?
The symbol, kV.A (not 'kva'), represents kilovolt ampere. A volt ampere (V.A) is the unit of measurement for apparent power, which is the vector sum of true power (in watts) and reactive power (in reactive volt amperes)
