Today we went over sinusoidal graphs that are represented as phasors, phasor math, and related phasors to solve ac circuits.
Above are components and relationships of sinusoidal graphs and some trigonometric identities.
Above we add too sin functions using the trig identities and then graph individual phasors.
On the right side of the picture we have the rectangular, polar, and exponential form that a sin can be written as and operations (phase angle operations are wrong, check below). The left side is an example using those operations.
The correct operation equations.
Above we practice the multiplication operations of phasors.
More examples of operations and converting to different coordinate systems.
Here we have an example where we use phasors to find current in the frequency domain.
Here are the relationships and how phasors for components(L,C) compare to R.
