Electric current (I) is defined as the rate of flow of electric charge (Q) per unit time (t). The relationship is given by Q = I * t.

Given the current (I) = 1.5 A and the time (t) = 10 ms. First, convert the time into seconds: 10 ms = 10 * 10^-3 seconds = 0.01 seconds. Now, calculate the charge: Q = 1.5 A * 0.01 s = 0.015 Coulombs (C).

The unit of electric current is the Ampere (A), and the unit of electric charge is the Coulomb (C). One Ampere is equal to the flow of one Coulomb of charge per second (1 A = 1 C/s). Milliseconds (ms) are a common unit of time, where 1 second = 1000 milliseconds.
