If the output of a NOR gate if fed to the input of a NOT gate,name the gate of the combination so formed.

If the output of a NOT gate is used as two inputs of an OR gate, name the gate of the combination so formed.

If the output of an OR gate is used as two inputs of a NAND gate, name the gate of the combination so formed.

If the output of a NOT gate is used as two inputs of an AND gate, name the gate of the combination so formed.

If two inputs of a NAND gate are joined, what type of a gate is formed?

If A and B are the two inputs of an AND gate, what will be the value of the output?

If A and B are the two inputs of an NAND gate, then the output will be

The outputs of a three-input OR gate and a three-input NAND gate will be same, if

Draw the symbol for two input NOR gate.

A wire of uniform cross section and length l has a resistance of 16 Omega . It is cut into four equal parts.Each part is stretched uniformly to length l and all the four streteched parts are connected in parallel. Calculate the total resistance of the combination so formed. Assume that stretching of wire does not cause any change in the density of its material.

Draw the symbol of a two input NOR gate.
