AC circuit: series or parallel RLC phasors — a TI-84 Plus CE program

By E-Code · updated

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.

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.
