Current = Power/Voltage. 11W/3v = 3.67Amps

Answer:

3.67 A

Step-by-step explanation:

The power rating is related to the voltage and the current by the following equation:


P=VI

where

P is the power rating

V is the voltage

I is the current

In this situation, we have:

P = 11 W

V = 3 V

I = ?

So, we can re-arrange the equation to calculate the current used:


I=(P)/(V)=(11 W)/(3 V)=3.67 A
