Delta-Resistor Calculator

This is a calculator which assumes you are able to short out and measure each resistor of this triangular resistor setup.

This is a black-box with 3 terminals exposed

Follow the bouncing ball...

1. Short out R1 (wire across a,b) to give you R2 in parallel with R3. See?
2. Measure resistance with probes at a,c. This is R_ac
3. Short out R2 (wire across b,c).
4. Measure resistance with probes at a,b. This is R_ab
5. Short out R3 (wire across a,c).
6. Measure resistance with probes at b,c. This is R_bc

I pity the fool that trusts this calculator!
