# 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 $${{params.I_ref}}\textrm{ A}$$ and a voltage of $${{params.V_ref}}\textrm{ V}$$, a lamp that contains a $${{params.P_bulb}}\textrm{ W}$$ bulb, an overhead light with a $${{params.P_light}}\textrm{ W}$$ bulb, and various other small devices adding up to $${{params.P_other}}\textrm{ W}$$.

## Part 1#

Assuming the power plant that supplies $${{params.V_pp}}\textrm{ V}$$ of electricity to the dorm is $${{params.d_pp}}\textrm{ km}$$ away and the two aluminum transmission cables have a diameter of $${{params.Al_d}}\textrm{ mm}$$, estimate the percentage of the total power supplied by the power company that is lost in the transmission.

## Part 2#

What would be the result if the power company delivered the electric power at $${{params.V_pp}}\textrm{ kV}$$?
