Question

Please help with the solution.

The rms value of a 60HZ single phase ac voltage source is 100V and its internal
resistance is 0.1 Q. Such voltage source is used to power a 12 resistive load. The wire
between the voltage source and the resistive load can be represented as 1mH inductor.
a)
Draw the equivalent circuit.
b)
Calculate the impedance of the wire.
What is the phasor of current in the wire?
c)
d) How much power can be delivered to the load in the steady state in this case?
*steady state means the current rms value will not change.
If a 100V dc voltage source is used instead to power the same resistive load with the
same wire,
e) How much power can be delivered to the load in the steady state in this case?
*steady state means the current dc value will not change.
f) Comparing the results in d) and e), what is your observation and why?
