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.
How much power P is received by the
facility?:...

1. In class we derived how a transformer can up or downregulate
the voltage in an electrical circuit with an alternating
current.
(a) Use the conservation of energy to deduce how the currents I1
and I2 must be related if you know the ratio of ε1/ε2 (for the
purpose of calculating the power delivered by a circuit ignore any
complications due to the fact that I(t) and ε(t) are
time-varying).
(b) In class I argued that power transmission is more...

A typical overhead power line is bare wire at a high potential relative to ground. A local line receives power at 3300 V with respect to the ground; the delivered voltage is slightly less, due to resistance loss in the wire. The wire is 10 km long, carries a current of 60 A, and has a resistance (made small to limit power loss) of 2.5 Ω. 1) Approximately how much power is lost due to the resistance of the wire?...
