What does an inductor choke do?
A choke is a type of inductor with or without a ferromagnetic core that is used to limit the rate of change over a range of frequencies in order to block, hence the name "choke," alternating current (AC), in a circuit while allowing lower frequency AC or direct current to flow (DC).
How does a choke coil work in circuit?
Because it can function as an inductor, the choke coil operates. A magnetic field is created in the coil when an AC current flows through, working against the current. Inductance is what prevents the majority of the AC current from going through.
How do choke coils make high voltage?
A coil, not a transformer, serves as the choke. A coil is surrounded by an electrical field when there is current flowing through it. When the coil's current is abruptly cut off, the field collapses and induction produces a high voltage.
