The electrical resistance of dry skin is 100 kω, but can be lowered to 20 ω if electrode contact area is large and conducting gel is used on the skin. if vmax of the defibrillatror 500 v and lasts 0.01 s, what is the maximum possible current delivered to the heart during defibrillation?

25 Ampers

Explanation:

As the current in a defibrillation is DC (Direct current), we can use simply the Ohm's law which shows:

V=I*R

Then if we want to know the current, we can follow the next step for I:

I=V/R

Using the information, and asumming electrode contact area is large and conducting gel is used on the skin (as is normal) , we can solve:

Imax=Vmax/R

Imax= 500 V / 20 ohms

Imax= 25 Ampers

*Fact: The time in this case doesn't make any difference in the result.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
