[#296] The MOSFET switch in its onstate may be considered equivalent to
Correct Answer

(A) Resistor

Explanation

Solution: Explanation: The MOSFET switch in its on state behaves like a resistor . When the MOSFET is on, the conducting channel is established between the drain and source terminals, and it allows current to flow through it with minimal resistance, making it act as a low-value resistor. Therefore, the correct answer is Option A: Resistor. Why the other options are incorrect: Option B: Inductor – An inductor stores energy in a magnetic field when current passes through it. A MOSFET in the on state does not function in this manner. Option C: Capacitor – A capacitor stores energy in an electric field and releases it when the circuit conditions change. This is not the behavior of a MOSFET in the on state. Option D: Battery – A battery provides a constant voltage or current in a circuit, whereas a MOSFET switch in its on state allows current to flow with minimal resistance, similar to a resistor, not a voltage source.
