Final answer:
The student's question about a MOSFET amplifier is best categorized under Engineering for a college-level course. It involves applying Ohm's law to analyze the behavior of the amplifier within an electric circuit.
Step-by-step explanation:
The correct answer is option Engineering. The question refers to a scenario involving a MOSFET amplifier and the use of Ohm's law to analyze a circuit that includes this semiconductor device.
When VDD is set to 20V, assuming this is the voltage supply for the MOSFET, and applying Ohm's law to any resistive components in the circuit, one can determine the current flow and potential voltage drops across those components.
This analysis is crucial for understanding the behavior of the MOSFET amplifier when subjected to certain electrical conditions.
It is important to remember that studying such electronic components and circuits are typically covered in electrical engineering or electronics engineering courses at the college level.
The correct answer is option Physics. This question is about a MOSFET amplifier circuit. MOSFET stands for Metal-Oxide-Semiconductor Field-Effect Transistor, which is a type of transistor used for amplification and switching signals.
In the circuit shown in Figure 3, it is assumed that the power supply voltage (Vdd) is 20V. This information is necessary to analyze and calculate the behavior of the amplifier.
