Chapter 10, Problem 4PC

Calculate the current that moves through your fingers (resistance $1000\Omega$) when you touch them to the terminals of a $6\text{-V}$ battery.

To determine

The current that moves through a person’s fingers.

Answer to Problem 4PC

The current moves through a person’s fingers is $0.006\text{A}$.

Explanation of Solution

Given info: The resistance of our finger is $1000\Omega$ and the voltage of battery is $6\text{V}$.

Write the expression for the voltage.

$I=\frac{V}{R}$

Here,

$V$ is voltage of battery

$R$ is resistance of our fingers

Substitute $1000\Omega$ for $R$ and 6 V for $V$ in the above expression to get $I$.

$\begin{array}{c}I=\frac{6\text{V}}{1000\Omega }\\ =0.006\text{A}\end{array}$

Conclusion:

Therefore, the current moves through a person’s fingers is $0.006\text{A}$.
