    0.032 Amperes

    Step-by-step explanation:

    in this question We are given;

    Voltage, V = 15.81 V Power, P = 500 mW (Milli-watts)

    We are required to determine the current, I

    We need to know that power, P is given by the product of current and voltage.

    That is;

    Power = VI

    But; 1 mW = 0.001 Watts

    Thus, 500 mW = 0.5 watts

    Rearranging the formula;

    I = Power : V

    = 0.5 watts : 15.81 V

    = 0.0316 Amperes

    = 0.032 A

    Thus, the current, I is 0.032 Amperes
