Use the current-voltage equation for the Na+ and K+ currents to
derive the GHK equation for the reversal potential for a channel
permeable to both Na+ and K+.
1. A sinusoidal voltage wave on a transmission line has real
amplitude, V_0. The wave is expressed in phasor form as
V_s(z) = V_0*e^(-alpha*z)*e^(-j*(beta)*z)
a. In which direction does this wave propagate and why?
b. Express the given wave in real instantaneous form.
c. The parameters of the line, operating at ω= 6.0×10^8 rad/s

Two long, parallel transmission lines 40.0 cm apart carry 20.0 A
and 80.0 A currents.
1)Find all locations where the net magnetic field of the two
wires is zero if these currents are in the same direction.
Enter your answer as two distances in centimeters, the
first distance from the wire carrying 20.0 A, and the second
distance from the wire carrying 80.0 A. Separate the values with a
comma.

Q \ What are transmission lines and what are the
effects and causes of transmission lines, then mention the
difference between the spread of electromagnetic waves in
transmission lines and spread in free space?
Derive the expressions of the average load voltage and current
in single-phase full-wave controlled rectifier (bridge rectifier)
and resistive load. Draw the waveforms of supply voltage, output
voltage, output current and thyristor current.
In a single-phase full-wave controlled rectifier (bridge
rectifier) and resistive load, it is desired to get an average load
voltage of 50 V. Determine the firing angle if the ac supply
voltage is 150 V. If the average load power is 300W, calculate the
average load...
