Secondary current = Primary current *(Number of secondary turns /Number of primary) turnsAnswerA current isn't 'induced' into the secondary winding of a transformer. It's a voltage that is induced into the secondary winding.Provided the secondary winding is connected to a load, the secondary voltage then supplies a secondary current which is determined from (Is = Vs/Rload). The primary current then depends upon the value of the secondary current and the turns ratio.
It depends on the turns ratio between the primary and the secondary. If the ratio were 10:1, a step-down transformer, for instance, the current in the secondary would be about 50A. If it were 1:10, a step-up transformer, however, the current in the secondary would be about 0.5A.AnswerThe primary current doesn't determine the secondary current. The secondary current is entirely-dependent on the secondary voltage and the impedance of the load. It is this secondary current that the determines the primary current. So you should be asking, "What value of secondary current would result in a primary current of 5.0 A?"
The secondary current is determined by the load, not by the transformer. For example, if the secondary voltage is 50 V and the load is 100 ohms, then the secondary current will be 0.5 A. If the load is 25 ohms, then the secondary current will be 2 A. It is important that a continuous secondary current doesn't exceed the rated secondary current of the transformer.
Your question reveals a misunderstanding of how a transformer works.The primary current of a transformer is determined by the secondary current, not the other way around. When the secondary voltage is applied to a load, a secondary current flows, and its value is determined by the secondary voltage and the load impedance. This secondary current then determines the value of the primary current.
The secondary current is determined by the load. So, divide the secondary voltage by the load impedance.
It does not have secondary air injection.

The current in the secondary when the voltage is twice the primary will be one half of the primary. The current in the primary when the voltage is twice the secondary will be twice the secondary.
The secondary current is calculated by dividing the secondary current by the impedance of the load. This value shouldn't exceed the secondary-winding's rated current except for short periods of time.
A one to one, i.e. isolation, transformer.CommentIt might be worth pointing out that the secondary current is determined by the load, and the primary current is then determined by the secondary current. The questioner appears to think that the secondary current is determined by the primary current.
The current flowing in the primary generates a magnetic field which induces a current in the secondary winding.AnswerNo current is induced into the secondary winding of a transformer. What is induced is voltage. Current will only flow in the secondary winding if it is connected to the load, and it is the load that determines the current, not the primary current.

The turns ratio of Primary / Secondary tells you have the voltage and current will be changed. The secondary current will be (primary turns/secondary turns) times the primary current, and the secondary voltage will be (secondary turns / primary turns) times the primary voltage.CommentThe above answer is a little misleading, because the secondary current is determined by the load, and not by the transformer's ratio. It would, therefore, be more accurate to say that the primary current would be equal to the secondary current times the (primary turns/secondary turns) -i.e. not the other way around!
The secondary current is determined by the load. So, divide the secondary voltage by the load impedance.
There are several ways to fix the secondary air injection system in a 2005 Chevrolet trailblazer. The most common fix is; changing the air filter.
