Answer: Please help! Electrical series circuits never make sence to me. I included the answer so that you can check your work. Hope that helps. 19. An electrical series circuit contains a resistor with a resistance of R- 20 ohms, a capacitor with a capacitance of C 0.01 farads, and an inductor with an inductance of L 1 henry. The initial current in the circuit is 0 amperes. A variable voltage of E(t) 120 sin volts of is applied to...

The resistor-capacitor network model we developed in Lecture (see figure below where it is shown only for the myelinated case) for the transmission of signals in nerve axons can actually be applied to both unmyelinated and myelinated nerve cells to estimate the propagation speed of a nerve impulse. In the unmyelinated case the 6-7 nm thick plasma membrane (the lipid bilayer) acts both as a (very thin) dielectric layer forming a capacitor between the inside of the axon and the...
