ओम का नियम -

V = IR

ओम के नियम का मूल अर्थ यही है इसी से आप नियम की परिभाषा बना सकते हैं

यहां

V = विभान्तर (Voltage), Volts में
I = धारा, करंट एम्पियर में
R = प्रतिरोध ओह्म में (Resistance)

परिभाषा - "समान ताप व स्थिति में किसी बन्द डीसी परिपथ में प्रतिरोध के सिरों पर लगने वाला वोल्टेज उस प्रतिरोध में प्रवाहित होने वाली धारा के मान के समानुपाती होता है ।"

अर्थात्

V∝ I

सरल भाषा -
किसी बंद डीसी परिपथ में वोल्टेज का मान उस परिपथ में प्रवाहित होने वाली विद्युत धारा और प्रतिरोध के मान के गुणनफल के बराबर होता है ।

यहां बंद डीसी परिपथ (Close DC Circuit) यानी की ऐसा डीसी सर्किट जिसमें स्विच ऑन हो और परिपथ चालू हो ।

इसमें
वोल्टेज (V) = धारा (I) × प्रतिरोध (R)

इसी फार्मूले का उपयोग करके आप वोल्टेज, धारा और प्रतिरोध के मान निकाल सकते हैं ।

जैसे
V = IR
R = V/I
I = V/R
