Parasitic power theft:

A power line running East-West at 150kVAC carrying a 75 MWatt load is 10 meters overhead. A thief makes a 100 turn loop of insulated copper wire around a plastic garbage can with a 70cm diameter. The voltage generated in this coil is used to charge batteries for a fish-finder, lights and radio in his fish hut. The battery charger is electrically equivalent to a 5 ohm resistor.

a) What orientation of the garbage pail winding will allow the greatest rate of electricity theft?

b) Determine the voltage generated across the battery charger.

c) Residential power costs $0.10/kWh. What is the value of the power stolen per day.

d) Why would metal can be a bad choice?


e) Above the indication is that the other wire for the AC power transmission is very far away. In fact they both hang from the same structure. If each wire carries a 100amp current and they are separated by 50cm, determine the force per unit length on the wires

From where highways404 (running north and south)and the 401(running east and west) cross in Toronto, car A is 100km north of the 401 travelling south (towards the 401) at the constant speed of 100km/hour. Car B is 200km west of the 404 travelling east (towards the 404) at a constant speed of 100km/ hour. Assuming both cars do not stop, find the time that the cars are at theirminimum distance from each other.? What is that distance?
