Question

All questions in Section 5(a) relate to the circuit below. This circuit will be shown at the start of each question. It is suggested that you first read each question; then carefully solve the circuit; and then enter your answers. Consider the figure below which shows the model for an AC power source connected to a pump via a pair of cables. RLOAD + LLOAD represent the pump. RWIRE represents the total resistance of the transmission wire (two cables each 750m long). The electricity cable has the following characteristics: Cross-section - circular Radius - 1.0 mm Material - Copper Resistivity - $1.68 \times 10^{-8}$ Ohm.m What is the value of the total resistance of the transmission cables, RWIRE? Enter your answer in Ohms. RWIRE Vs 240V RMS 50 Hz LLOAD=22 mH RLOAD=10 ?
