There is a huge range of electric values between a minimum value and a maximum value of a standard electric unit. For example, the resistance of a conductor can be as low as 0.001 ohms and as high as 100000 ohms. We can avoid writing multiple zeros while describing the values of the el...
Defined in the context of static electricity, voltage is the measure of work required to move a unit charge from one location to another, against the force which tries to keep electric charges balanced. In the context of electrical power sources, voltage is the amount of potential energy avail...

Resistivity is the inverse of conductivity (resistivity = 1/conductivity) and is a measure of the ability not to conduct (i.e. resist) electrical current.The unit of measurement is ohms/m (Ωm).Resistivity is often used to measure the quality of pure water. ...
