संकल्पना:

एक ट्रांसफार्मर में,वोल्टेज और घुमाव की संख्या निम्न प्रकार से एक दूसरे से संबंधित होते हैं।

\(\frac{{{V}_{1}}}{{{V}_{2}}}=\frac{{{N}_{1}}}{{{N}_{2}}}\)

जहाँ,

 V1 = ट्रांसफार्मर के प्राथमिक पक्ष में वोल्टेज 

V2 = ट्रांसफार्मर के द्वितीयक पक्ष में वोल्टेज 

N1 = ट्रांसफार्मर के प्राथमिक पक्ष में घुमावों की संख्या

N2 = ट्रांसफार्मर के द्वितीयक पक्ष में घुमावों की संख्या

गणना:

V1 = 2000

V2 = 200

N2 = 100

\(\frac{2000}{200}=\frac{{{N}_{1}}}{100}\)

N1 = 1000
