Chapter 34, Problem 36A

How much current moves through your fingers (resistance: 1200 ohms) if you touch them to the terminals of a 6-volt battery?

To determine

To Calculate: The amount of current that moves through the fingers.

Answer to Problem 36A

  $0.005\text{A}$

Explanation of Solution

Given:

Resistance, $R=1200\Omega$

Voltage, $V=6\text{V}$

Formula Used:

Current can be calculated using Ohm’s law:

  $I=\frac{V}{R}$

Here, V is the voltage and R is the resistance.

Calculations:

Substitute the values and solve:

  $\begin{array}{l}I=\frac{V}{R}\\ I=\frac{6\text{V}}{1200\Omega }=0.005\text{A}\end{array}$

Conclusion:

Thus, the amount of current that moves through the fingers is $0.005\text{A}$ .
