Questions & Step-by-Step Solutions
In a differential amplifier, what is the output voltage if both inputs are equal?
Step 1: Understand what a differential amplifier does. It takes two input voltages and amplifies the difference between them.
Step 2: Identify the two inputs of the differential amplifier. Let's call them Input A and Input B.
Step 3: If both Input A and Input B are equal, it means there is no difference between them.
Step 4: Since the differential amplifier amplifies the difference, if there is no difference (both inputs are equal), the output will be zero.
Step 5: Therefore, when both inputs are equal, the output voltage of the differential amplifier is 0V.
Differential Amplifier Functionality – A differential amplifier amplifies the difference between two input voltages. If the inputs are equal, the difference is zero, resulting in a zero output voltage.
