AC circuit: series or parallel RLC phasors — a TI-84 Plus CE program
ACPHASOR is a TI-BASIC program for the TI-84 Plus CE. Series or parallel R, L, C on a sine source: impedance magnitude and angle, current, real and reactive power, power factor, and the resonant frequency — leave L or C at 0 when the circuit has none.
What it asks for and what it shows
It asks for 5 values at its prompts, after you pick option 1 from its menu. In the example below it shows Z OHM, ANG DEG, I A, P W, Q VAR, PF, F0 HZ.
Example run
One of its oracle test cases: “series RLC 120 V 60 Hz”. The inputs are typed in order, and the results are the values the case expects on the screen.
| Step | Value |
|---|---|
| You enter | |
| Menu | option 1 |
| Input 1 | 120 |
| Input 2 | 60 |
| Input 3 | 10 |
| Input 4 | 0.05 |
| Input 5 | 0.0001 |
| The screen shows | |
Z OHM= | 12.60654946 |
ANG DEG= | -37.51081015 |
I A= | 9.518861635 |
P W= | 906.0872682 |
Q VAR= | -695.5368636 |
PF= | 0.7932384696 |
F0 HZ= | 71.17625434 |
How it's checked
5 test cases, each checked against an independent method. Replayed key by key on a virtual TI-84 Plus CE, they make 38 checks.
How E-Code checks every program
Run it or put it on your calculator
- Open the library in the TI-84 Plus CE calculator and pick “AC circuit: series or parallel RLC phasors” (ACPHASOR).
- Put it on your own calculator with a computer and a USB cable, or type it in by hand.
