Hello every body, those who are willing to learn Electrical Engineering from basic level, Kinda join me. I will be posting content.

Question

kenljw · Answer

V =I  R     P = I V        P = I^2 R
I = V/R    P = V^2/R
V  volts across a component of delivered by source
I   amperes, current through a component of delivered by source
R  resistance in Ohms
P  watts, power comsumed by compoent or deliverd by source
These are very basic equations and units in electrical/electronic courses

rvc · Answer

basic is the ohm's law
:)

kenljw · Answer

Yes, the first equation I gave, then further developement.

rvc · Answer

then comes V rms I rms 
in DC analysis we have mesh,nodal,superposition,thevinins....

kenljw · Answer

RMS is an abreviation for root mean square in reverse order, it essential represents a signal power corresponding to a DC equivalent, ie effective power.
in DC analysis we have mesh,nodal,superposition,thevinins....
These are common means of analysis of an electric/electronic circuits and are used in DC, AC, and signal analysis.
