संकल्पना:

  • मचा नियम: स्थिर तापमानात, विद्युतप्रवाह वाहून नेणाऱ्या वायरमधील संभाव्य फरक हा त्यातून वाहणाऱ्या विद्युतप्रवाहाच्या थेट प्रमाणात असतो.

          म्हणजे V = IR

जेथे V = संभाव्य फरक, R = रोध आणि I = विद्युतप्रवाह.

गणना:

दिलेले V = 18 V आणि R = 3 Ω,

  • मच्या नियमानुसार:

⇒ V = IR

⇒ I = V/R

⇒ I = 18/3 = 6 A
