Question

A transformer has 15 turns in its primary and 6750 turns inits secondary. If the potential difference across the primary is1.2 V, what is the potential difference across the secondary? A transformer has 15 turns in its primary and 6750 turns inits secondary. If the potential difference across the primary is1.2 V, what is the potential difference across the secondary? A transformer has 15 turns in its primary and 6750 turns inits secondary. If the potential difference across the primary is1.2 V, what is the potential difference across the secondary?

Explanation / Answer

Transformer ratio is (Vs / Vp) = (Ns /Np) Here Vs = potential difference across the secondarycoil Vp =potential difference across the primary coil = 1.2V Ns = numberof turns in the secondary coil = 6750 turns Np = numberof turns in the primary coil = 15 turns By substituting all these values in the above formula we get Vs =(6750turns)(1.2V) / (15turns) = 540 V
