What happens to the output of an operational amplifier when the input voltages are equal?
Step 1: Understand that an operational amplifier (op-amp) has two input terminals: one is called the inverting input (-) and the other is called the non-inverting input (+).
Step 2: When you apply voltages to both inputs, the op-amp compares these two voltages.
Step 3: If the voltage at the non-inverting input (+) is equal to the voltage at the inverting input (-), it means there is no difference between the two inputs.
Step 4: The op-amp is designed to amplify the difference between the two input voltages.
Step 5: Since the difference is zero (because the voltages are equal), the output of the op-amp will also be zero.
