Suppose that the resistance between the walls of a biological cell is 6.8 × 109 ω. (a) what is the current when the potential di
GenaCL600 [577]
(a) We can find the current flowing between the walls by using Ohm's law:
I= \frac{\Delta V}{R}
where \Delta V=69 mV=0.069 V is the potential difference and R=6.8\cdot 10^9 \Omega is the resistance. Substituting these values, we get
I=1.01 \cdot 10^{-11} A

(b) The total charge flowing between the walls is the product between the current and the time interval:
Q=I \Delta t
The problem says \Delta t=0.86 s, so the total charge is
Q=(1.01\cdot 10^{-11} A)(0.86 s)=8.73 \cdot 10^{-12} C

The current consists of Na+ ions, each of them having a charge of e=1.6 \cdot 10^{-19} C. To find the number of ions flowing, we can simply divide the total charge by the charge of a single ion:
N= \frac{Q}{e} = \frac{8.73 \cdot 10^{-12}C}{1.6 \cdot 10^{-19}C} = 5.45 \cdot 10^7 ions
