Draw the equivalent circuit of a transmission line and hence write the transmission line equations for an elemental section of a transmission line.

Expert Solution

The equivalent circuit of a transmission line for an incremental portion, of a transmission line has been drawn below:

Transmission line equations:

Let us consider an elemental portion, of a two wire transmission line as shown in the above figure:

By applying KVL we get:

Applying KCL at node P we get:

Now, as Vs(z) and Is(z) are the phasor forms of V(z,t) and I(z,t) respectively

Equations 5 and 6 are the transmission line voltage and current wave equations.

Draw an equivalent circuit and list the sequence of steps to connect jumper cables properly between two car batteries when trying to jump-start a car with a run-down battery. Be sure to label both the positive and negative terminals on each battery and the red and black cables of the jumper. I t is recommended that the last connection you make should be between the black jumper cable and the run-down car; and instead of connecting it to the negative...
