WebAug 9, 2024 · The SI unit of electrical current is the ampere, defined as 1 coulomb/second. Current is a quantity, meaning it is the same number regardless of the direction of the flow, without a positive or negative number. However, in circuit analysis, the direction of current is relevant. The conventional symbol for current is I, which originates from the ... WebOhm’s law explains the relationship between the three characteristics of the electrical circuit: the electron flow, the resistance to flow in the wire or other conductor, and the pressure (called "voltage") we have in the circuit.
