In the following circuits, PN-junction diodes Dl, D2 and D3 are ideal for the following potential of AB, the correct increasing order of resistance between A and B will be - 

The output Y of the combination of gates shown is equal to:

In a silicon diode, the reverse current increases from $$10\mu A$$ to $$20\mu A$$. when the reverse voltage change from $$2V$$ to $$4V$$. The reverse ac resistance of the diode is

How many NOR gates are required to form NAND gate:

A two inputed XOR gate produces an high output only when its both inputs are:

When all the inputs of a NAND gate are connected together, the resulting circuit is:

In a zener diode, break down occurs in reverse bias due to

In the adjacent circuit, A and B represent two inputs and C represents the output. The circuit represents.
