A 200 volt (r. m. s) generator having an internal resistance of 200 ohm is feeding a loss-less transmission line. The characteristic impedance and the length of the line are 200 ohm and 10 m respectively. The line is terminated in a resistive load of 100 ohm. If the operating frequency is 37.5 MHz calculate the

Current drawn from the generator.

Magnitude and phase of the current flowing in the load.

Power delivered to the load.
