FAQ
What is the Drain Current?
Drain current below threshold voltage is defined as the subthreshold current and varies exponentially with gate to source voltage. Drain Current is usually measured using the Milliampere for Electric Current. Note that the value of Drain Current is always positive.
Can the Drain Current be negative?
No, the Drain Current, measured in Electric Current cannot be negative.
What unit is used to measure Drain Current?
Drain Current is usually measured using the Milliampere[mA] for Electric Current. Ampere[mA], Microampere[mA], Centiampere[mA] are the few other units in which Drain Current can be measured.
