Q. |
The 'Choke' used with a tube light is basically – |
A. | an inductor |
B. | a capacitor |
C. | a transformer |
D. | a resistor |
Answer» A. an inductor | |
Explanation: In electronics, a choke is an inductor used to block higher-frequency alternating current (AC) in an electrical circuit, while passing lower-frequency or direct current (DC). In a tubelight, the high voltage is created by suddenly interrupting the current in choke, which is connected in series with the tubelight. |
