| Ampere |
The constant current which when flowing through two parallel wires 1 m apart would produce in vacua a force of 2 x 10 -7 N/m |
A |
| Coulomb |
The quantity of if electricity when a current of 1 ampere flows for 1 second |
C |
| Volt |
The electromotive force or potential difference when a constant current of 1 ampere produces a heat in resistance at the rate of 1 newton-meter (joule)/second |
V |
| Ohm |
Is the electrical resistance of a conductor in which a constant curent of 1 ampere flow under a constant voltage of 1 volt |
ω |
| Henry |
The inductance in which 1 volt is produced by a currrent changing at the rate of 1 ampere/second |
H |
| Farad |
The Capacitance in which 1 couomb is stored for a potential difference of 1 volt |
F |
| Siemens |
The unit of electrical conductance S = A / V |
S |
| Joule |
The unit of energy work and quantity of heat. the work done when the point of application of a force of 1 newton is displaced through a distance of 1 metre in the direction of the force |
J |
| Watt |
The unit of power = t Joule/second |
W |
| Weber |
The unit of magnetic flux. The magnetic flux linking a circuit of one turn produces in it an electromotive force of 1 volt as it is reduced to zero at a uniform rate in 1 second |
Wb |
| Tesla |
The unit of magnetic flux density. The tesla is equal to 1 weber per square metre of circuit area |
