MOSFET: When the gate voltage is large with respect the the threshold voltage Vth, the voltage drop from drain to source is linearly dependent on current (for small voltages << Vth of the MOSFET), so it behaves like a resistor. While the current between drain and source should ideally be zero when the transistor is being used as a turned-off switch, there is a weak-inversion current, sometimes called subthreshold leakage.
