Basic Electrical theory

I couldn't take it that I only made a 76% so did a lil refresher on series and parallel circuit calcs and retook the test. This time I got a 92%. Much better!

Most of the info in figure 2 was not needed. All you needed was the total voltage, total amperage, and PF to solve the two questions that I remember being asked.

Apparent power = V x A

True Power = watts = V x A x cos(angle)

TP = In-phase amps x Volts.

They gave the in-? amps and volts, so the PF wasn't necessary for the TP..........chim

TP = In-phase amps x Volts.

They gave the in-? amps and volts, so the PF wasn't necessary for the TP..........chim

They also gave the total amps, volts, and power factor, so the in phase current wasn't necessary.

I did pretty good. 92.

The definitions had no business being there. They aren't even definitions.
Most of them didn't even make sense. Light is not what happens when photons strike blah blah blah... and that was the most sensible one of all.
