संकल्पना:

दिलेले व्होल्टमीटर आदर्श मानू जेणेकरून व्होल्टमापीचा प्रतिरोध अनंत असेल.

आता प्रश्नात दिलेल्या परिपथ आकृतीमध्ये व्होल्टता  भागाकार नियम लागू करून.

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 प्रतिरोधात व्होल्टता

V2 = R2 प्रतिरोधात व्होल्टता

V = एकूण व्होल्टता

गणना:

दिलेले आहे: V = 5 V

F1 Shraddha Uday 24.12.2020 D3

म्हणून, 1kΩ मध्ये व्होल्टेज आहे,

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

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