A normal human heart, beating about once per second, creates a maximum 4.00 mV potential

maximum electric strength is 0.016 V/m

Explanation:

given data

Potential V = 4 mV = 4 × V

potential across = 0.250 m

Frequency f = 1 Hz

solution

we get here electric field that is

E =   ...................1

put here value and we get

E =  

E = 0.016 V/m

maximum electric strength is 0.016 V/m
