Depending on which elements of the planetary gear system are transferring or not determines the gear ratio. An automated transmission usually has multiple planetary gear set. This configuration creates a bit greater gear ratio than the primary configuration. But the input gear continues automotive gears to be spinning sooner than the output gear . This results in the planetary gear delivering extra torque, or energy, to the the rest of the drivetrain. This configuration would likely be in play as your automobile hastens from a useless stop, or when you’re driving up a hill.
