Logic Gates (AND and OR)

What is the function of a logic gate?

• To supply voltage to a circuit

• To perform logical operation

• To provide resistance to a circuit

• To ensure the current flows only in one direction

Which of the following shows the operation of an AND gate?

• A+B = Output

• A-B = Output

• AxB = Output

• A/B = Output

Which of the following shows the operation of an OR gate?

• A+B = Output

• A-B = Output

• AxB = Output

• A/B = Output

A truth table consists only of 1 and 0

• TRUE

• FALSE
