{'fluorescent tubes': [0, 1, 0, 0], 'choke coil': [0, 0, 1, 0], 'low frequency currents': [0, 1, 0, 0], 'choke': [0, 1, 0, 0], 'circuit': [0, 0, 1, 3], 'line voltage': [0, 1, 1, 0]}
The choke coil in a fluorescent tube lighting system is responsible for reducing the current in the circuit. It is designed to limit the current flowing through the tube and prevent it from exceeding safe levels. The choke coil works by creating a magnetic field that opposes changes in current, which effectively limits the current flow.
Therefore, the correct answer is:
reduce current in the circuit
