$($i$)$ Two E$-$MOSFETS are connected in series across a $10$V supply. The $$upper$$ MOSFET has its drain connected directly to its gate. The $$lower$$ MOSFET is unbiased. The input to the circuit is taken to be the gate of the lower MOSFET and the output is taken to be at the drain of the lower MOSFET. The upper MOSFET has a resistance of $2$K$$ when its gate$-$source voltage is $10$V$.$ The lower MOSFET has a resistance of $150$ when the input voltage is $3$V$.$ What is the output of the circuit when the input to the circuit is $0$V and $3$V respectively?
