An inductor
A capacitor
A transformer
A resistor
Answer is Right!
Answer is Wrong!
The correct answer is: A. An inductor.
An inductor is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. An inductor’s ability to store energy is measured in inductance, which is typically measured in henries (H).
The choke used with a tube light is an inductor that is used to suppress high-frequency noise. The choke is typically made of a coil of wire that is wound around a core of ferromagnetic material. When current flows through the choke, it creates a magnetic field that opposes the change in current. This opposition to change in current helps to suppress high-frequency noise.
The other options are incorrect because:
- A capacitor is an electrical component that stores energy in an electric field.
- A transformer is an electrical component that transfers electrical energy from one circuit to another.
- A resistor is an electrical component that resists the flow of electric current.
