# Worksheet: AND Gates

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?

- A
- B
- C
- D

**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.

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

What is the value of p in the table?

What is the value of q 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 is 1, input is 0, and input is 1, what is the output?
