AC Electrical Circuit Analysis: Series RLC Simulation

In this video we explore series RLC circuits via simulation with TINA V12 Student Edition. This version of TINA has a phasor diagram generator, unlike TINA-TI.

Hi sir,
Is it possible to get two different answers when calculating voltage of a component? For instance, using ohms law (i*Z) for resistor, or voltage divider rule (v*(X/Z))?

Not if you do it correctly. In AC circuits, a common beginner's error is to ignore the phase angles. In such a case, you can come up with different (incorrect) values.
Consider it this way: ultimately, the voltage divider rule is just a convenient form of Ohm's law. To keep it simple, consider two resistors, R1 and R2, in series with source E. The "long way" using Ohm's law is to find the current (I=E/Rtotal), and then multiply that result by the resistor of interest (e.g., VR1=I*R1). If you substitute the original expression for I in that second equation, you get VR1 = (E/Rtotal)*R1, which can rewritten as VR1 = E*(R1/Rtotal) (voltage divider rule).
