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 3.06 min, how many conduction electrons pass through your heart?

Answer 1

Explanation:

Given that,

Current passes through our chest is 0.3 A

The current persists for 3.06 minutes

We need to find the number of conduction electrons pass through your heart. Charge flowing divided by time equals current. Also, q = ne

$I=\dfrac{ne}{t}\\\\n=\dfrac{It}{e}\\\\n=\dfrac{0.3\times 3.06\times 60}{1.6\times 10^{-19}}\\\\n=3.44\times 10^{20}$

So, $3.44\times 10^{20}$ electrons would pass through your heart.
