Chapter 21, Problem 58P

To determine

The impedance of the body for this to occur

Answer to Problem 58P

Solution:

The impedance of the body for this to occur will be $1.7\times {10}^3\text{Ω}$

Explanation of Solution

Given:

$\begin{array}{l}f=60\text{Hz}\\ I=70\text{mA}\\ V=120\text{rms}\end{array}$

Formula Used:

$Z=\frac{V_{rms}}{I_{rms}}$

Where,

$\begin{array}{l}f=60\text{Hz}\\ I=70\text{mA}\\ V=120\text{rms}\end{array}$

Calculation:

$\begin{array}{l}Z=\frac{V_{rms}}{I_{rms}}\\ =\frac{120\text{V}}{70\times {10}^{-3}\text{A}}\\ =1.7\times {10}^3\text{Ω}\end{array}$
