Define $1 \ Coulomb$ in terms of $1 \ Ampere$.

(N/A) The relationship between electric current $(I)$,charge $(Q)$,and time $(t)$ is given by the formula: $I = \frac{Q}{t}$.
Rearranging this formula to solve for charge,we get: $Q = I \times t$.
By definition,$1 \ Ampere$ is the flow of $1 \ Coulomb$ of charge per second $(1 \ A = 1 \ C/s)$.
Therefore,$1 \ Coulomb$ is defined as the quantity of electric charge that flows through a cross-section of a conductor in $1 \ second$ when a steady current of $1 \ Ampere$ is maintained in the conductor.
