Effective Voltage in MOSFET Formulas

Effective voltage is the equivalent DC voltage that would produce the same amount of power dissipation in a resistive load as the AC voltage being measured. And is denoted by V_ov. Effective Voltage is usually measured using the Volt for Electric Potential. Note that the value of Effective Voltage is always negative.
