A particular extension cord can support up to 8 amps. Mo has an iron whose label states 1,200 watts and wonders if the iron can be plugged into the extension cord. If watts are converted to amps by dividing by 120, how many amps does the iron use?

Answer:

10 A

Step-by-step explanation:

 

Given data  

Current in cord is  I  = 8 a m p

Power of iron is   P = 1200 W

Voltage converted is  

V = 120 V

The power can be expressed as

[tex]P=IV=\\I=\frac{P}{V}[/tex]

Substitute the given value in above we get,

I = [tex]\frac{1200}{120}= 10amps[/tex]

Thus, the current use by iron is  

10 A
