Very good. A logic circuit and a logic gate are capable of processing only one Binary Digit or bit at a time (0 or 1). What do think 0 and 1 mean?
You’re right. How about the electricity that passes through the circuit? Remember, we are now dealing with electronics.

That’s correct. 0 or 1 represents the absence or presence of current or electricity. They also specify the results for different combination of two conditions:
0 1
Off On
No Yes
Closed Open
Low High
(There will be a visual aid containing this table.)
Again, what is a logic gate?

There are three basic types of logic gates – AND, OR and NOT.
Lets first discuss the AND gate.
What do we mean by the word “and”?
What does it imply about the function of the AND gate?

Very good. Can you remember a type of circuit that works like the AND gate?

You’re right. Can you explain how a series circuit works? Please go in front and use the series circuit I prepared. (There will be a series circuit mounted on an illustration board.)

Thank you. AND gate works like that. Here is an improvised AND gate which also shows its symbol. Please describe it. The left side is the input side and the right is the output side.
(It will look like the figure below.) Thank you. A and B are the input and Q is the output. If the switch is closed, it means an input 1 and if open, an input 0. If the diode lights, it means an output of 1 and 0 if not.
Now, ___1___ and
