You create a transformer by wrapping wire around an iron nail. The number of turns are: Primary (500); Secondary (2500). The Primary voltage is 3.00 V. The Secondary current is 200 mA. This is like Examples #14 and #15 (pages 16 & 17) of Chapter 21 notes. 13) Calculate the Secondary voltage (V). 14) Calculate the primary current (A).

Answer:

Explanation:

This is a step up transformer

v₁ /v₂ = n₁ /n₂ = I₂ /I₁

3/V₂ = 500/2500

V₂ = 15 V .

500/2500 = I₂/I₁ =

I₁ = 5 X 200 mA. = 1000 mA.
