Question

A 6 ohm load is connected to a 120volt source through a pair of 0.25 ohm conductors. Calculate (a) the load current and voltage, b) the voltage drop in h line wires.

Answer 1

(a) the load current and voltage:

$$I=V/(r_c+r_l)=120/(2·0.25+6)=18.5\text{ A}.\\ V_l=Ir_l=18.5·6=111\text{ V}.$$

(b) the voltage drop in h line wires.

$$V_d=Ir_c=18.5·(2·0.25)=9.25\text{ V}.$$
