Lesson Worksheet: AND Gates Physics

Start Practising

In this worksheet, we will practice determining the input and output of AND gates in logic circuits and completing truth tables for AND gates.

Q1:

Which of the following symbols represents an AND gate?

Q2:

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.

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

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?

Q4:

The diagram shows an AND gate. If input A is 1 and the output is 0, what must input B be?

Q5:

AND Gate
Input A	Input B	Output
0	0	0
0	1
1	0	0
1	1

The truth table shows the output of an AND gate for various combinations of inputs.

What is the value of in the table?

Q6:

The diagram shows two AND gates, where the output of the first AND gate is one of the inputs to the second. If input A is 1, input B is 0, and input C is 1, what is the output?

Q7:

Each of the diagrams shows a logic circuit consisting only of AND gates. Which of the diagrams shows circuits where the output has a value of 1?

Q8:

The diagram shows a logic circuit consisting of three AND gates. How many different possible combinations of input values are there for this circuit?

Q9:

The diagram shows a logic circuit consisting of three AND gates. How many of the inputs must have a value of 1 in order for the output to have a value of 1?

Q10:

The diagram shows a logic circuit consisting of three AND gates. How many of the inputs must have a value of 0 in order for the output to have a value of 0?
