Thanks for your unique explaination 😊
Good explanation thank you so much sir
You're most welcome
Sir book me 120W Diya h?
thnksss bhaiiya
Well done 👍🏼 sir☺️
Best and easiest explaination
Tqqqq
Thank you sir
Welcome
Thanks sir💖
Most welcome
Thanks genius
Welcome 😊

Sir book k ans..kuch or h
120 hai na yaar
Then use
P=VI
P=120×15
P=1800J/S
This is the long answer
Allah huakbar
Jai shree ram ❤🙏
Jai shree Ram 🚩📿
Given,
R=8
I=15
t=2
H=?
V=?
We know,
H=I²×R×t
=15²×8×2
=3600
Now,we have,
H=V.I.t
3600=V.15.2
.........
.....
V=120
Which is the answer...
Ye answer kitap mein hai sir😭

Then use
P=VI
P=120×15
P=1800J/S
This is the long answer
@@black_soul-9920 use sir method its fast
Bhai t = 2hours
Si unit me convert krke hoga
T= 7200seconds
Answer is 1800joule per sec
