Question -
In the circuit as shown in figure, A and B represent two inputs and C represents the
Options:
A .  OR gate
B .  NOR gate
C .  AND gate
D .  NAND gate
E .  35 mA
Answer: Option A : A The circuit represents OR gate, as the output at C is 1, when either A or B or both A and B have input at level 1. But output at C is zero, when both A and B are at zero level and the Boolean expression is C = (A + B).
