Lesson: AND Gates

In this lesson, we will learn how to determine the input and output of AND gates in logic circuits and complete truth tables for AND gates.

Sample Question Videos

Q1:

Which of the following symbols represents an AND gate?

Q2:

Input A	Input B	Input C	Output
0	0	0	0
0	0	1
0	1	0	0
	1	1	0
1	0	0	0
1	0	1	0
1	1	0
	1	1	1

The diagram shows two AND gates connected as part of a logic circuit. The truth table shows the output for the various combinations of the inputs.

What is the value of in the table?

Q3:

The diagram shows an AND gate. If input A is 1 and input B is 1, what will the output be?
