భావన:

ఇచ్చిన వోల్టమీటర్ ఆదర్శంగా ఉండనివ్వండి, తద్వారా వోల్టమీటర్ యొక్క నిరోధకత అనంతంగా ఉంటుంది.

ఇప్పుడు ప్రశ్నలో ఇచ్చిన వలయం రేఖాచిత్రంలో వోల్టేజ్ విభజన నియమాన్ని వర్తింపజేయడం ద్వారా.

F1 Shraddha Uday 24.12.2020 D2

\(V_1=\frac{R_1}{R_1+R_2}\times V\)

\(V_2=\frac{R_2}{R_1+R_2}\times V\)

V= R1 నిరోధకతపై వోల్టేజ్

V2 = R2 నిరోధకతపై వోల్టేజ్

V = మొత్తం వోల్టేజ్

లెక్కింపు:

ఇవ్వబడింది =: V = 5 V

F1 Shraddha Uday 24.12.2020 D3

కాబట్టి, 1kΩ వద్ద వోల్టేజ్,

\(V_1=\frac{R_1}{R_1+R_2}\times V\)

\(V_2=~\frac{1}{1\; +\; 4}\times5=1~V\)
