భావన:

ట్రాన్స్‌ఫార్మర్ యొక్క మలుపు నిష్పత్తి (n) ఇలా ఇవ్వబడింది

\(n = \frac{{{N_1}}}{{{N_2}}} = \frac{{{E_1}}}{{{E_2}}} = \frac{{{I_2}}}{{{I_1}}}\)

Where,

N1 = ప్రాథమిక వైపు మలుపుల సంఖ్య

N2 = ద్వితీయ వైపు మలుపుల సంఖ్య

E1 = ప్రైమరీ సైడ్ వోల్టేజ్

E2 = సెకండరీ సైడ్ వోల్టేజ్

I1 = ప్రాథమిక కరెంట్

I2 = సెకండరీ కరెంట్

లెక్కింపు:

ఇచ్చినవి-

n = 2, E2 = 100 V

∴ \(2 = \frac{{{E_1}}}{{{100}}} \)

E1 = 200 V
