# In my experiment on transformers, the data showed

• Chezz42
In summary, the conversation is about an experiment conducted on a transformer with two tightly wrapped coils using AC currents. The experimenter measured the voltage with varying distances between the two coils, using an iron core and an air core. The results showed a linear relationship between distance and voltage with the iron core, but an inverse function with the air core. The experimenter is curious about the implications of this for wireless charging and seeks clarification from an expert.

So I did an experiment a this week on the relationship between two tightly wrapped coils with same length and number of coils in a transformer. This was in a compete circuit using AC currents. I measured the Voltage, keeping the currents the same. One experiment had an iron core between the two coils and I varied the distance between the two coils and got a linear relationship. When I used an air core, the relationship between distance and voltage became and inverse function. I don't understand why.

Hello Chezz, and

Aren't your notes or textbook supposed to help you in this ? No background amterial anywherer in sight ? This experiment does have a context, though, I suppose ?

Well, I did this experiment on my own and was wondering about how wireless charging works. I think i figured out myself, but thanks for dropping by to help.

Kudos for this initiative to find out ! I think you're on the right track. Closeness of sender and receiver and high frequencies are key in wireless charging I think, but I'm no expert. Let's ask @CWatters !
