Question

A power factor of 1 indicates that maximum power is being delivered. True or False?

For an inductor the voltage lags the current through it by 90 degrees. True or False ?

For a purely resistive element, the voltage and the current through the element are in phase. True or False?

The Length of a phasor is called the modulus or magnitude. True or False?

The more reactive the loaf, the lower the factor. True or false?

Answer 1

For the beginner tech they use ELI the ICE man, which mean Voltage leads Current in an Inductor(by 90 degrees0, Current leads Voltage in a Capacitor(by 90 degrees)
v = L di/dt i = sin(omega t), v = omega L cos(omega t)
i = C dv/dt v = sin(omega t) i = omega C cos(omega t)
v = i R , no angular component, thata = 0
Power factor = cos(thata) thata the angle between Voltage and Current
Power factor = 1 purely resistive

Answer 2

Oh yes, "ElI the ICE man" Haven't heard that for while very good @KenLJW what about the resistor marking color code? lol.

Answer 3

I learned the resistor color code in the Navy but its a little risqué. I'll enter it if requested.

Answer 4

Nah, I figured you knew it. lol
