an inductor coil when consume no energy is called
Correct answer: B. choke
- A. a coil
- B. choke
- C. toroid
- D. none
Explanation
An inductor coil that consumes no energy is called a "choke" or an "inductive choke." A choke is an inductor designed specifically to block or "choke" high-frequency alternating current (AC) while allowing direct current (DC) or low-frequency signals to pass through with minimal resistance.Chokes typically have a high inductance and low resistance, which makes them efficient at filtering out high-frequency noise in electronic circuits. When an alternating current flows through a choke, the changing magnetic field induces a back EMF (electromotive force) that opposes the change in current. This property helps the choke to smooth out current fluctuations and maintain a more stable current flow.In summary, an inductor coil that consumes no energy and is used to filter out high-frequency noise is called a choke or an inductive choke

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
