(5, 6) RL/RC circuits

In RL circuit, how to find phase difference angle?

Phaser diagram addition to find 90° triangle, then angle at origin is angle of phase difference OR cos-1(A/H)

What is fleming’s impedance triangle?

A right-hand triangle with R (resistance) as the adjacent, XL (inductive reactance) as the opposite, and Z (V/I) (impedance) as the hypotenuse.

What is the relationship between inductive reactance and phase angle?

Provided resistance stays the same, the higher the inductive reactance the larger the phase angle difference

How to find total impedance of circuit?

Z = square root of resistance squared and capacitive/inductive reactance squared

How to find total current of series RL/RC circuit?

V / square root of resistor squared + reactance squared
