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.
