QUESTION ONE

1. List four (4) parameters that determine the performance of a transmission line. (2marks)

 

The four parameters that determine the performance of a transmission line is conductance, resistance, inductance and capacitance.

1. RESISTANCE: Resistance is stated in ohms per meter length of a line and its represent the imperfection of a line. In other words, it obstruct or resist the flow of current in a circuit. It’s measured in ohms [Ω]

CAPACITANCE: It is
