What is the current flowing through the given circuit? $A$ given diode is an ideal diode.

When a semiconducting device is connected in series with a battery and a resistance, a current is found to flow in the circuit. If, however, the polarity of the battery is reversed, practically no current flows in the circuit. The device may be

If in a $p-n$ junction diode,a square input signal of $10\, V$ (varying from $+5\, V$ to $-5\, V$) is applied as shown,then the output signal across $R_L$ will be:

The electrical resistance of the depletion layer is large because

Two ideal diodes are connected to a battery as shown in the circuit. The current supplied by the battery is......$A$

In the following circuit shown in the figure,three diodes are connected,each with a forward resistance of $40 \Omega$ and infinite backward resistance. The current through the $100 \Omega$ resistance is: (in $mA$)
