The resistance of a resistor is reduced to half of its initial value. If other parameters of the

sir i have doubt is heat and energy formula same i mean both things are same in conductor?

[@sarathiacademyjeeneet]

Yes, they are same. The energy generated in the resistor is the heat which it liberates in the surrounding.

Sir in what cases the current will remain unchanged but voltage will be changed?(reverse of the question asked)

[@sarathiacademyjeeneet]

The question will mention it explicitly. This happens in Constant Current Source. However, if question mentions, we need to assume that and carry out the calculations.

[@selmonbhai4790]

Sir question Mein mention hai ki other parameters are unaltered to current bhi to other parameters Mein Aaya aur Agar current other parameters Mein Nahin Hai To voltage ko kyon other parameters Mein Humne Dala ya Hamen Kaise Pata Chala ki voltage hi unaltered hai

[@sarathiacademyjeeneet]

If we take voltage and current both as other parameters, then the question is unsolvable as R = V / I. And V and I remaining same, but R changes is impossible. Therefore, one must change. In this, we take V to be same as in the circuit, we have Battery. Battery is a component of a circuit to provide Potential Difference. Thus, V is same and I changes.

Thanks sir for making video on that topic ❤

thank u so much ❤❤❤

Welcome!!

[@SHAAN.20]

but there is not mention that V is constant?

[@sarathiacademyjeeneet]

"Other parameters are unaltered". This statement takes care that the V is unchanged. Wishing you all the best. For joining our online batches, please WhatsApp us on 8292 356 357.

[@advaithjadhav4472]

sir can we not substitute I as 2I because I is inversely proportional to R AND WHEN WE USE THE FORMULA i^2rt ... we get twice as the answer ?

[@sarathiacademyjeeneet]

Yes we can do that surely. Point is to take care and see what isn't changing and what's changing. If we just somehow mindlessly put the formula without taking into consideration that 'i' value has changed, then answer will become wrong.
