Question

V=15.81 V, P = 500 mW, I=

Answer 1

0.032 Amperes

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
