Q.23 Why is electrical power required at all when the elevator is descending? Why should there be a limit on the number of passengers in this case?
When the elevator is descending, then electric power is required to prevent it from falling freely under gravity.
Step 2: Interprete about the limit on the number of passengers.
Also, as the weight inside the elevator increases, its speed of descending increases. therefore, there should be a limit on the number of passengers in the elevator to prevent the elevator from descending with large velocity.
