Question: 1 / 400

What does R2 control in the context of a DC break coil?

Discharging path for the break coil

In the context of a DC brake coil, R2 is primarily responsible for providing a discharging path for the brake coil. When the brake is released, the energy stored in the coil needs to escape to prevent sustained braking and ensure that the system can function correctly. If R2 serves as a discharging path, it allows the coil to safely release the stored energy, effectively bringing the system back to a state where it can operate without the braking effect.

While other options mention functions related to control and charging, they do not accurately describe the role of R2 in the discharging process. Understanding the importance of R2 in this capacity is critical for maintaining the functionality and safety of the elevator system, as it directly impacts how the brake responds and disengages when necessary.
