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

गैस + विलायक ↔ विलयन + ऊष्मा
गैस का द्रव में घुलना एक ऊष्माक्षेपी प्रक्रम है। ताप बढ़ाने पर साम्य बायीं ओर विस्थापित होता है और विलयन से गैस मुक्त होती है।

Raoult's Law states that "For a solution containing non volatile solute, at a given temperature, the relative lowering of vapour pressure is equal to mole fraction of the solute.
i. e. p'/p=x.
Limitations :
1. Raoult's law is applicable only to very dilute solutions. Raoult's law is applicable to solutions containing non-volatile solute only.
2. Raoult's law is not applicable to solutes which dissociate or associate in the particular solution.
