OR gate;
An OR gate has two or more inputs with one output. It operates in such a way that the output is high if one of the two input is high.
AND gate
An AND gate has two or more inputs with one output. It operates in such a way that the output is high when both the outputs are high.
NOT gate
It has a single input and single output .If input is 0 the output is 1, if input is 1 the output is 0.
PROCEDURE
Working of or gate:
1. Do not plug the switches A, B. Record the glow of the bulb.
2. Now plug A and record the glow of the bulb.
3. Now plug B and record the glow of the bulb.
4. Now plug A, B. Record the glow of the bulb.
Working of and gate:
1. Do not plug the switches A, B. Record the glow of the bulb.
2. Now plug A and record the glow of the bulb.
3. Now plug B and record the glow of the bulb.
4. Now plug A, B. Record the glow of the bulb.
