We have needs to a specific unit for any measurements, which can
easily specify to anything by its unit.
The Si units is widely used, such as every where most common Si
units that everyone can easily understand.
So we will discuss about some electrical units which is mostly
used in electrical engineering,
The some electrical units are following.
1- Volt
The "Volt" is used for measure electrical potential
difference, and also "Voltage" and "EMF" called to
electrical potential.
The unit of voltage denoted by "V", and it check by volt
meter, the volt meter always used in parallel.
2- Current
The Ampere is the unit of electrical current it used for measure
electrical current and "ion flow", the "ion flow"
also called to electrical current,
The unit of current denoted by letter "i", and the current check by "Ampere" meter, the Ampere or current meter always used in series, and also series meter called to Ampere meter.
3- Watt
The Watt is the unit of electrical power it used for measure
electrical power.
The unit of power denoted by letter "W” and the power check by "Watt" meter, the watt meter always used in parallel but like this diagram.
4- Ohm
The Ohm is the unit of resistance it used for measure resistivity,
the resistance basically opposite flow of the free electrons or current, means
it resist to current from flowing, for this we use ohm meter for measure
resistance of any wire or equipment which is unit is "Ohm".
The unit of resistance denoted by this symbol "Ω", and it check by this way.
5- Hertz
The Hertz is the unit of frequency it used for frequency checking
in any circuit.
The unit of frequency denoted by letter "Hz", and the frequency check by "Hertz" meter, the Hertz meter always used in parallel.
6- Farad
The Farad is the unit of capacitance it used for measure the
capacitance of capacitors.
The unit of Farad denoted by letter "F”, and the Farad check
by "Capacitance multimeter", the capacitance meter always used in
parallel.
7- Columb
The columb is the unit of electrical charge it used for measure
electrical charge, when one ampere current flow for one second it will equal to
one columb.
The unit of Columb denoted by letter "C", and also its
meter exist which measure the electrostatic charge.
8- Henry
The Henry is the unit of inductance it used for measure coil
inductance.
The unit of inductance denoted by letter "H”, and the inductance check by "Henry" meter, the Henry meter always used in parallel of coil.
9- HP
The Hp is the unit of electrical power it basically used for
measure to electrical Motor power, because Motor rating always in Hp.
The full form of Hp is "Horse power", and the Horse
power denoted by "hp", it can't measure by any meter, it always
measure by electrical Watts meter, when the 1Hp is equal
to 746 watts.
10- Weber
The Weber is the unit of magnetic flux it used for measure
magnetic flux in the motor and transformer windings, the unit of magnetic flux
denoted by this symbol "Φ" or Wb.
The magnetic flux measure by calculation.
