Transformers - Investigating the Turns Ratio Equation

In this video I investigate the transformer turns ratio equation:
V₁ / V₂ = N₁ / N₂
This video shows the collection of primary and secondary p.d. readings for a range of turns ratios using a pair of double coils. One coil is a pair of 60 turn coils; the other is a pair of 120 turn coils. So turns combinations such as N₁ = 60 and N₂ = 120 and N₁ = 120 and N₂ = 240 can be investigated. By connecting voltmeters across the primary and secondary coils I measure the primary and secondary p.d.s.
In the analysis video (coming soon…) I will use a combination of a column graph (chart) and correlation analysis to investigate the validity of the ratio equation.
There is a worksheet to go with this experiment so that you can attempt the data analysis yourself. And the spreadsheet that I use is available as a free download. Get them both via the website here: physicshq.wixsite.com/alevelp...
Experiments with waves, like this one, are good practice for mandatory practicals for many physics specifications, such as OCR physics A, AQA A-Level physics, Edexcel A-Level physics, CPAC, PAG, practical endorsement.
Relevant concepts: transformers, potential difference, voltage, ratios, coil turns, linear correlation.
