Primary coil of a step-up transformer has number of turns than secondary coil.
Primary coil of a step-up transformer has number of turns than secondary coil.
- A. more
- B. less
- C. same
- D. cant say
Step-by-step solution
In a step-up transformer, the secondary voltage is higher than the primary voltage. According to the transformer equation Vp/Vs = Np/Ns, for Vs > Vp, we have Np < Ns, meaning the primary coil has fewer turns than the secondary coil.
