Electric current is the flow of electric charge through a conductor per unit time, predominantly carried by negatively charged electrons. The rate of this charge flow is measured in amperes. Conductance measures how easily charge flows through a material, while resistance indicates how strongly a material opposes electric flow.
Electric current is the flow of electric charge through a conductor per unit time. In most cases, this flow is constituted by the movement of negatively charged electrons along the conductor. The rate at which this charge flows is measured in amperes (A), with 1 ampere being equal to 1 coulomb per second.
When an electric current flows through a wire, it can be likened to water current moving through a pipe. Just as we count water molecules flowing past a section of a pipe to define water flow, we count the number of electrical charges passing through a section of a conductor to define electric current. The ability of a material to allow charge to flow through it easily is called conductance, while the measure of how strongly a material resists the flow of electric charge is known as resistance.
