            Conversion Calculators
            Formulas, equations, and calculation tools for most compliance engineering applications.


            Ohm’s Law
            Ohm's Law is valid for circuits that contain only resistive elements (no capacitors or inductors). Ohm's Law is true for voltage and current (DC) or (AC).


            Effective Impedance
            Effective Impedance is the DC resistance plus the additional apparent impedance caused by inductance and capacitance at a specified frequency.


            Voltage to dB Converter
            This function converts the linear relationship between two voltages or powers into decibels, and decibels in power or voltage gain or attenuation.


            Voltage Dropped & Power Dissipated Across a Series Resistor
            Power dissipation is a measure of how much power is converted into heat in a circuit due to inefficiencies.


            Compliance Voltage
            Compliance voltage represents the maximum voltage a current source will reach as it attempts to produce the desired current at the desired rate of change.


            Decibel Conversion
            Converts between decibels, voltage (or current) gain, and power gain.


            Watts to Joules Conversion
            Convert watts to joules by entering the power in watts and time in seconds using this easy calculator.
