Q: When the input of a two input logic gate are 0 and 0, the output is 1. When the inputs are 1 and 0, the output is zero. The type of logic gate is

The truth table for a NOR gate is as given.It is a combination of OR and NOT gate.The output out of an OR gate for both inputs 0 is 0.The NOT gate would turn it into 1.The output out of an OR gate for inputs 1 and 0 is 1.The NOT gate would turn it into 0.Therefore,the logic gate is NOR gate.

Q: The logic gate represented in given figure is

\$P\$ is the output of the inputs signal \$A\$ and \$B\$ operating on a \$NOR\$ gate. Then the signal \$P\$ (A' and B') acts as input signal for the second \$NOR\$ gate to give the output \$Y\$.Thus writing truth table for each step gives the table as shown above which resembles the truth table of an \$OR\$ gate for input signal \$A\$ and \$B\$ whereas the \$Y\$ as the output signal.

Q: In the given circuit, the voltage across the voltage across the load is maintained at 12V. The current in the zener diode varies from 0-50 mA. What is the maximum watage of the diode?

The voltage drop across the diode and the load are same because they are connected in parallel. The maximum current through the diode is 50mA. Thus, the maximum power dissipated in the diode will be 50mA times 12V = 0.6W

Q: The circuit as shown in figure, the equivalent gate is

Let the outputs of individual gates be labelled as X, Y and Z respectively starting from left to right. we have:\$Z=\overline { Y } \\ Y=\overline { XX } =\overline { X } +\overline { X } =\overline { X } \\ X=\overline { A+B } \\ \Rightarrow Z=X=\overline { A+B } \$.Thus, the combination behaves as NOR gate.
