Question

A current of 0.300 A through your chest can send your heart into fibrillation, ruining the normal rhythm of heart beat and disrupting the flow of blood (and thus oxygen) to your brain. If that current persists for 1.58 min, how many conduction electrons pass through your heart?

Answer 1

Answer:

Around $1.7752248*10^{20}$

Explanation:

First, let's convert those minutes in seconds;

$1.58min*\frac{60s}{1min}=94.8s$

Now,  let's convert from amperes to electrons per second using the conversion factor given by:

$1A=6.242*10^{18} electrons-per-second$

So:

$0.3A*\frac{6.242*10^{18} }{1A} =1.8726*10^{18} electrons-per-second$

Finally, multiply the previous result by the time in seconds:

$Total-electrons=(1.8726*10^{18})*(94.8)=1.77522248*10^{20}$
