3. In the circuit shown: $V_{DD} = 15 V$ and $R_D = 3.9 \Omega$. According to the data sheet for this NMOS, the gate threshold voltage is $V_{GS(TH)} = 1.7 V$ and $R_{ds(on)} = 20 m\Omega$ and can be used as an estimate for any condition where this MOSFET is ON. Calculate $i_D$, $V_{DS}$ and the power dissipated in the NMOS for: a. $V_G = 0.75 V$ b. $V_G = 10 V$
