Velocity of Wave Propagation power system analysis free pdf download
The velocity of propagation is therefore related to the values of L and C. If the inductance and capacitance of the rf line are known, the time required for any waveform to travel the length of the line can be determined. To see how this works, observe the following relationship: Q = IT
This formula shows that the total charge or quantity is equal to the current multiplied by the time the current flows. Also:
Q = CE
This formula shows that the total charge on a capacitor is equal to the capacitance multiplied by the voltage across the capacitor If the switch in the figure below is closed for a given time, the quantity (Q) of electricity leaving the battery can be computed by using the equation Q = IT. The electricity leaves the battery and goes into the line, where a charge is built up on the capacitors. The amount of this charge is computed by using the equation Q = CE.
