When using P=VI, we get answer 50. *Why can't we use that formula and why is it wrong?* Here is what I did: First I found Current (I) when Voltage is 220V and Power is 100W, then I used the formula P=VI to find the Power when Volatge is 110V and Current is 5/11A. Please tell what's wrong here.

[padhiarsuresh]

Sir, can we solve question no . 3 by using this P= VI??? PLEASE REPLY....

[prabhabisht]

Because V is directly proportional to I so in this question V is changed in second part so I will also change that's why we used P=V²/R because R is constant in the question

[zechamp]

P=V²/R R=V²/P
After equating both the resistance as they are of same bulb we will get the answer 25W

[Parthkothari]

Pls start magnetic effect of electric current

[YOURbaba-cwfi]

Video start - 2:02
Thanks 👍 me later

[prashantkumarkuntal]

Sir why didnt you use P=VI instead of P=V²/R ??

[anithbineesh]

Sir i have a doubt
In 3rd question
Sir when i use the equation p=VI i get the answer 50 why is it like that sir🤔🤔 so is my answer wrong

[lifeisstruggle-]

In 2019

Abhishek sir= OMG 300 people.... very good guys..

In 2020

Abhishek sir = guys only 300 what r u doing?

[saurabhdwivedi]

Sir sir sir plzz reply dejea ga
In Q3 why we can't use p=vi???

[anirudhpoddar]

08:55 Sir, in this connection, will the electric current flowing through bulb will be same or different. Means, is I constant in both the cases ?

[surajgupta]

U will soon reach to 1 million subscribers 🔥🔥

[SilverGate]

Sir but P - VIT also
I considered them directly proportional and got 50 watt in last question

[hiiiiiiiiiiiiiiiiiman]

P proportional hai V ke saath

Agar P 2 guna badhega toh V bhi 2 guna badhega,

Toh agar P 2 guna ghat raha hai toh V kyu nahi??? P = VI

[prem]

Sir, magnetic effect of current kab shuru hoga ??

[himachalisher]

Good afternoon sir
I have a doubt why we haven't used
P=VI formula in Q3??

[vaibhavsharma]

Mere sare doubts ho gye saaf kyoki Abhishek sir hai physics ke baap

[sAkshAm_]

It took me 4 time to do the Q3 with other methods
Thanks a lot sir
It helped

[ldk]

Sir because of l did so well in mid terms

How can you cut R with R when it's multiplying with each other. When it reciprocals the R comes with multiply with the pther R. Please give the explanation about my doubt.
