An overhead line having the surge impedance of 400 Q is connected to a short length of cable of surge impedance of 50 Q. A travelling wave of constant magnitude of 80 kV and infinite duration originates in the overhead line and travels towards the junction with cable. Find the energy transmitted for a duration of 3 usec into the cable after the wave has arrived at junctions.

Consider the circuit shown in Figure 1. V1 is a 7.2 kHz sine wave with an amplitude of 4 V.Figure 1: RC Circuit Schematic1. Determine the total impedance (Z) of the circuit.2. Using V1 as a zero-phase reference, calculate the values of the following:a) Amplitude and phase of current (I)b) Amplitude and phase of voltage across R1 (VR1)c) Amplitude and phase of voltage across C1 (VC1

Why is the negative effect of stray capacitance more pronounced in very high frequency circuits?

Add the two voltages below together (phasor voltages are RMS). ?ଵ =60 ? ∠ 0° ?ଶ =80 ?∠ 270° a) What is the resultant as a phasor using RMS voltage and degrees? b) What is the resultant voltage as a sinusoidal equation if the frequency is 100 Hz?
