Conductance (also known as electrical conductance) is defined as the potential for a substance to conduct electricity. Conductance is the measure of how easily electrical current (i.e. flow of charge) can pass through a material. Conductance is the inverse (or reciprocal) of electrical resistance, represented as 1/R.

WebThe ampere, symbol A, is the SI unit of electric current. It is defined by taking the fixed numerical value of the elementary charge e to be 1.602 176 634 x 10 -19 when expressed in the unit C, which is equal to A s, where the second is defined in terms of Δ νCs .
