Power Transmission To Dorm

Power Transmission To Dorm#

A physics student has a single-occupancy dorm room. The student has a small refrigerator that runs with a current of params.Iref A and a voltage of params.Vref V, a lamp that contains a params.Pbulb W bulb, an overhead light with a params.Plight W bulb, and various other small devices adding up to params.Pother W.

Part 1#

Assuming the power plant that supplies params.Vpp V of electricity to the dorm is params.dpp km away and the two aluminum transmission cables have a diameter of params.Ald mm, estimate the percentage of the total power supplied by the power company that is lost in the transmission.

Please enter a numeric value.

Part 2#

What would be the result if the power company delivered the electric power at params.Vpp kV?
