Key Introduction What is a Quadratic Equation?
... Algebra - Rearranging and Solving Quadratic Equations The quadratic formula states that for a quadratic equation of the form y equals ax squared plus bx plus c, the value of x is equal to negative b plus or minus the square root of b squared subtract 4ac, all divided by 2a. For example, for the quad ...

... an n-channel FET, -ve for a p-channel FET), a drain current (ID) flows and can be controlled via a gate-to-source bias voltage VGS. (2). ID is greatest when VGS = 0, and is reduced by applying a reverse bias to the gate (negative bias in an n-channel device, positive bias in a p-type). The magnitude ...
