When considering the dimensions of electric charge, which fundamental units must be combined to express it in terms of SI base quantities?
current and time
Electric charge is defined as the product of electric current and the time for which it flows, expressed by the relation \(Q = I \times t\).
The SI unit of charge, the coulomb, is therefore equal to one ampere-second (1 C = 1 A s).
In dimensional terms, charge has the dimensions of current (A) multiplied by time (T), written as \([Q] = [A\,T]\).
Hence, electric charge is expressed by combining the base quantities current and time.
