In Fig. an 8-Ω heater is connected to the 120-Ωac power line by two 50-ft lengths of copper wire. If each 50-ft length of wire has a resistance of 0.08 V, then calculate the following:
a. The total length of copper wire that connects the 8-Ω heater to the 120-Vac power line.
b. The total resistance, RT, of the circuit.
c. The current, I, in the circuit.
d. The voltage drop across each 50-ft length of copper wire.
e. The voltage across the 8-Ω heater.
f. The I 2R power loss in each 50-ft length of copper wire.
g. The power dissipated by the 8-Ω heater.
h. The total power, PT, supplied to the circuit by the 120-Ωac power line.
i. The percentage of the total power, PT, dissipated by the 8-Ω heater.
