What is choke in electrical? A choke, also known as an inductor, is a two-terminal electrical component that consists of a coil of wire. What is the primary function of an electric choke? An electric choke warms the screen and opens to block high-frequency signals while allowing the passage of direct current and lower frequencies of alternating current. Why is the use of a choke important in electronic devices? Chokes help eliminate potential malfunctions by suppressing electromagnetic interference (EMI) and radio frequency interference (RFI) in power supply lines. What is the key consideration when selecting or designing the right choke? Careful observation and knowledge of the specific application requirements are essential for choosing the correct choke.
