Front	Back
I. Represents	Electrical flow or Current
I. is measured in	Amps ( or amperes)
E. Represents	Electrical Pressure
E. is measured in	Volts (voltage)
R. Represents	Opposition of current flow. Resistance
R. is measured in	Ohms
3 basic formulas of Ohms Law	I=E/R , E=I*R , R=E/I
R_{Total = Total Current}	R₁ + R₂ + R₃ + R₄ All resistance is Added together to find R Total (R Add)
I_{Total= Total Amps}	I₁ = I₂ = I₃ = I₄ ...etc I Total are all the Same around a circuit._{(I Same)}
E_{Total= Total Volts}	E₁ + E₂ + E₃ + E₄ ...etc All voltage(E) is Added together to find total volts used. (E Add)
P. Represents	Power
P. is measured in	Watts
P= (formula)	I (Amps) * E (Volts)
