An electric utility company supplies a customer's facility from
the main power lines (effective voltage
V0=150 V) with two copper wires. Each
wire has diameter d=5.28 mm and length
l=34.83 m. The customer load current is known to
be I=191.5 A.
What is the voltage V at the customer facility
for the given load current?:
V= ___ V.
How much power P0 is delivered by
the main lines?:
P0= ___ kW.

In order to achieve less environmental pollution there is a tendency of using electric vehicles now. There are three major units in an an electric car as shown in the following block diagram. Battery Unit Control Unit Motor/ Generator The battery unit consists of a low voltage (12 V) battery and a high voltage (about 200 V) battery. 12 V battery is used to supply power for horn, lamps, wipers etc. High voltage battery drives the electric motor which then...
