Electrical Symbols, Formulas (Formulaes) & Equations Used in the Electrical Industry.

[a1]

Listed here is the webpage that I have put together containing the "Electrical Symbols, Formulas (Formulaes) & Equations Used in the Electrical Industry".

As soon as I get time I will put on the level Three (3) formulas, as well as the ones used to work out problems in the 302 & 303 written exams.

I hope you make good use of them.

Un-pinned as sadly the lined page no longer exists

for one of your last formula's, supply voltage, should that be for impedance and not voltage?

Thanks Admin

I think a couple are wrong!!

Power is the rate at which work is done so

Power = Work / Time (shown as Power = work x time)

And the voltage calculation works if your talking about the Voltage across the resistor and the voltage across the Inductor so the symbols should read Vr and Vxl not just R and Xl.

The calculation shown would give impedance using resistance and inductive reactance as stated by andyc

Power = Work / Time (shown as Power = work x time)

Patchy concurs with msb :|

I shall correct them on the next update - Thank You Gentlemen.
