Question

A normal human heart, beating about once per second, creates a maximum 4.00 mV potential across 0.250 m of a person's chest, producing a 1.00 Hz electromagnetic wave. What is the maximum electric field strength produced?

Answer 1

Answer:

maximum electric strength is 0.016 V/m

Explanation:

given data

Potential V = 4 mV = 4 × $10^{-3}$ V

potential across = 0.250 m

Frequency f = 1 Hz

solution

we get here electric field that is

E = $\frac{V}{d}$   ...................1

put here value and we get

E = $\frac{4\times 10^{-3}}{0.250}$  

E = 0.016 V/m

maximum electric strength is 0.016 V/m

Answer 2

Answer:

Explanation:

Potential difference, V = 4 mV = 0.004 V

distance, d = 0.25 m

The relation between the electric field strength and the potential difference is given by

V = E x d

0.004 = E x 0.25

E = 0.016 V/m

Thus, the maximum value of the electric field is 0.016 V/m.
