Question

What are the lights on during service in main cabin?

Answer 1

During service in the main cabin, the lights may dim momentarily when certain electrical equipment is turned on due to a temporary decrease in voltage caused by electrical resistance within the circuit.

Step-by-step explanation:

During service in the main cabin, the lights may dim momentarily when certain electrical equipment is turned on or activated. This is because these electrical devices draw a large amount of current, causing a temporary drop in voltage.

A similar phenomenon can be observed in everyday situations. For example, when you turn on the motor in your refrigerator, the refrigerator light may dim momentarily. The same can happen when you start the engine of a car and the passenger compartment light dims.

This effect occurs due to a temporary decrease in voltage caused by the electrical resistance within the circuit. As the electrical device starts operating, it requires a surge of current, which leads to a voltage drop and a temporary decrease in light intensity.
