When calculating power exhausted through a resistive element, remember … power varies directly with the square of the voltage and inversely with the resistance.
Therefore, if your resistance has a tolerance of ±5%, your input voltage can only have a tolerance of ±sqroot(5) if you’re going to meet that power output required in your specification.
The “We’re in tolerance! No, you’re not!” discussion went back-and-forth before about five minutes before I made that minor note.
You see, that MSMS education taught me something.
Mrs. Perry would be proud!
Also, isn’t it a bit weird for the same quality group that will sign off on product testing to be the individuals actually running the test? It’s a matter of integrity tied up in checks-and-balances.
[Somewhere in West Tennessee, my dad probably just choked on his water, reading that.]
I love this job!
