In this reference sheet, ElectricalandElectronicsEngineering.com presents a reference formula for fundamentals principles and rules in electric circuits.
Voltage, resistance, and current are the three basic properties of electric circuits:
SI unit of voltage is volts
SI unit of resistance is ohms
SI unit of current is amps
How to Solve Resistors in Series
Two or more resistors are solved in series by simply adding them.
i.e R(eq) = R1 + R2 + … Rn
How to Solve Resistors in Parallel
Two or more resistors in parallel are solved using formula.
