What happens to the output of an operational amplifier when the input voltage exceeds the supply voltage?
Step 1: Understand that an operational amplifier (op-amp) has a power supply that provides a maximum voltage level.
Step 2: Know that the input voltage is the voltage you apply to the op-amp's input terminals.
Step 3: Realize that if the input voltage goes higher than the maximum voltage provided by the power supply, the op-amp cannot produce a higher output.
Step 4: When the input voltage exceeds the supply voltage, the op-amp's output will reach its maximum limit, which is called saturation.
Step 5: In saturation, the output voltage will stay at this maximum level and will not increase even if the input voltage continues to rise.
