In a p+n junction diode under reverse bias, the magnitude of electric field is maximum at
A. The edge of the depletion region on the p-side
B. The edge of the depletion region on the n-side
C. The p+n junction

To prevent a DC return between source and load, it is necessary to use
A. Resistor between source and load
B. Inductor between source and load
C. Capacitor between source and load
D. Either A or B
It is a GATE question. In all the books answer is 'c' . MOSFET has high on state conduction losses, So, I also think answer should be 'a'-

A mosfet is said to be on if Vgs>Vth. Ones it is on, then it will act as a resistor for signal given at the drain and source terminal. The resistance offered can be varied by changing vgs. So I feel it should be A. Please do correct me if I am wrong.
