Connecting a step-up transformer backward

[Alameda]

Homework Statement

Suppose the inner and outer solenoids are used as the primary and secondary coils respectively, and the inner solenoid is connected to the Output Ports of the signal generator on 850 interface as shown in figure 2. If the signal amplitude from the signal generator on 850 interface is set to 10V, the 850 interface will be crashed. Why? (hint: resistances of inner is 0.2 and outer is 77 ohms)

Relevant Equations

Vp> Vs step up transformer
Vs

I deduced that this is a step-up transformer wired backward because of the number of turns in each coil. The inner coil has a less number of terms and by the problem's wording, the inner coil is the primary coil. I'm not sure what would actually happen, a hypothesis (that I am not confident on) would be that the current, which is proportional to the resistance of each coil, needs more current when traveling from the outer coil to the inner coil?

Welcome to PhysicsForums.

Is there a drawing that goes with this question? It's difficult for me to decode what is being hooked to what, especially if the problem says that the signal generator will be damaged. The signal generator is driving one coil of a transformer, and the other coil is open-circuited?

All that was given was this, there is an inner coil and an outer coil. I got the machine picture to make things more clear.

the inner coil goes into the outer coil, in the apparatus you can only see the outer coil because the inner coil is inside

Ah, I understand now. Yeah, if you put 10Vpp into the smaller coil, the step-up-effect will generate a large output voltage. It sounds like you are using the same instrument to drive one coil and observe the other coil, right?

If the same (gauge) wire is used to wind the primary and secondary coils, you can estimate the ratio $\frac{N_p}{N_s}$ from the two resistances, which you are given. Can you say why that is true?
