**Q- We are given a circuit as follow:**

**Identify the above circuit as an AND or OR gate. Explain using negative and positive logic.**

**Ans: ** We assume the voltage levels of +5V & 0V. So if we give both inputs as 0V then output would be 0V too. Similarly we obtain other cases as given in the table below:

**This is the truth table for AND gate.**

**Hence we can the circuit given would act as AND gate in NEGATIVE LOGIC while as OR gate in POSITIVE LOGIC**
