Which of the following is the correct formula of Electric current (I) in terms of charge (Q) and time (t)?

I = \(\frac{Q}{t}\)

If a net charge Q, flows across any cross-section of a conductor in time t, then the current I, through the cross-section is

I = \(\frac{Q}{t}\)

The SI unit of electric charge is coulomb (C), which is equivalent to the charge contained in nearly 6 × 10¹⁸ electrons. (We know that an electron possesses a negative charge of 1.6 × 10^–19 C.)

The electric current is expressed by a unit called ampere (A), named after the French scientist, Andre-Marie Ampere (1775–1836).
