    Mnemonic expression for remembering what the variables represent in Ohm's Law for electrical calculations.

    I=A, Intensity (Current)=Amperes
    E=V, Electromotive Force=Volts
    R=O, Resistance=Ohms
    P=W, Power=Watts

    See also "PIE in your EIR". P=IE. E=IR.

    Remembering the above allows one to solve algebraically almost any electrical equation.

    For the same, expressed in a different way, see PIER=WAVO.
