Calculating circuit values

One thing you may need to do is calculate what components you might need to make a circuit work.

The one formula you will need to remember is Ohm’s Law is E=I/R where E = electromagnative force (voltage), I = current (amps), and R = Resistance (ohms). You can of course move these variables around if you need to calculate I or R of the circuit: I = E/R R = I/E

There are some basic principals to constructing a circuit you will need to follow, and depending on which type of circuit you are making, the rules are slightly different. Here are the basics of each circuit type.
