Question
A transformer has 1000 turns in the primary and 100 in
the secondary coil. If input voltage is 220 V, output voltage is:Solution
Transformers work on the principle: Vs/ Vp = Ns /Np. Substituting, Vs =100/1000 × 220 = 22V. Since fewer turns in the secondary, it's a step-down transformer.
If DBC = 18 and GFE = 36, then IJEF =
