Drain Current in MOSFET Formulas

Drain Current is the current flowing from the drain terminal to the source terminal, controlled by the voltage applied to the gate. And is denoted by I_D. Drain Current is usually measured using the Ampere for Electric Current. Note that the value of Drain Current is always negative.
