Chapter 18: Problem 103

In a pacemaker used by a heart patient, a capacitor with a capacitance of $25 \mu \mathrm{F}\( is charged to \)1.0 \mathrm{V}$ and then discharged through the heart every 0.80 s. What is the average discharge current?

Short Answer

Expert verified
Answer: The average discharge current is \(31.25\mu \mathrm{A}\).

Step by step solution

01

Calculate the charge stored in the capacitor

Using the formula for the charge stored in a capacitor, Q = CV, we can find the charge Q stored in the capacitor. In this case, the capacitance C is given as \(25\mu \mathrm{F}\) and the voltage V is given as \(1.0\mathrm{V}\). $$ Q = CV = (25\mu \mathrm{F})(1.0 \mathrm{V}) = 25\mu \mathrm{C} $$
02

Calculate the average discharge current

To calculate the average discharge current, we can divide the charge Q by the discharge time interval t, which is given as \(0.80\mathrm{s}\). $$ I_\text{avg} = \frac{Q}{t} = \frac{25\mu \mathrm{C}}{0.80\mathrm{s}} = 31.25\mu \mathrm{A} $$ The average discharge current is \(31.25\mu \mathrm{A}\).

Near Earth's surface the air contains both negative and positive ions, due to radioactivity in the soil and cosmic rays from space. As a simplified model, assume there are 600.0 singly charged positive ions per \(\mathrm{cm}^{3}\) and 500.0 singly charged negative ions per \(\mathrm{cm}^{3} ;\) ignore the presence of multiply charged ions. The electric field is $100.0 \mathrm{V} / \mathrm{m},$ directed downward. (a) In which direction do the positive ions move? The negative ions?

We can model some of the electrical properties of an unmyelinated axon as an electric cable covered with defective insulation so that current leaks out of the axon to the surrounding fluid. We assume the axon consists of a cylindrical membrane filled with conducting fluid. A current of ions can travel along the axon in this fluid and can also leak out through the membrane. The inner radius of the cylinder is \(5.0 \mu \mathrm{m} ;\) the membrane thickness is \(8.0 \mathrm{nm} .\) (a) If the resistivity of the axon fluid is \(2.0 \Omega \cdot \mathrm{m},\) calculate the resistance of a 1.0 -cm length of axon to current flow along its length. (b) If the resistivity of the porous membrane is \(2.5 \times 10^{7} \Omega\).m, calculate the resistance of the wall of a 1.0 -cm length of axon to current flow across the membrane. (c) Find the length of axon for which the two resistances are equal. This length is a rough measure of the distance a signal can travel without amplification.
