the angle of the voltage minus the angle of the current.

So we can use this information to determine what that difference in the two

phase angles are.

Our voltage is supplied by the power company and

a certain current is supplied by the power company.

There's a line voltage of 0.08 ohms associated

with the path from the power company to the customer,

and we'll take that into the count as well.

So, the first thing we want to find if we're looking for

the power supplied by the power company to the given 480 V load,

is we need to find the current Is.

And we're going to work in RMS terms.

Remember, the RMS, in the case of current,

if we have a sinusoidal current with an amplitude of I sub m,

then our RMS value is going to be I sub m divided by squared root of 2.
