kaunsa question
OpenStudy (mayankdevnani):
de do dhakka , tumhare liye jaan hazir
OpenStudy (samigupta8):
If we have an energy source which supply a constant current into the load,if its internal resistance is.

Kya options btau yaa ni
OpenStudy (mayankdevnani):
batao zara
OpenStudy (samigupta8):
Resistance of load
Zero
Very large as compared to load resistance
Non zero bt less dan resistance of load
OpenStudy (mayankdevnani):
is the answer zero ?

answer is zero
OpenStudy (mayankdevnani):
As you said earlier,
\[\large \bf V=I(r+R)\]
where,
\[\large \bf R=resistance~of~load~~~and~~~r=internal~resistance\]
OpenStudy (samigupta8):
Correct....
OpenStudy (mayankdevnani):
\[\large \bf I=\frac{V}{R+r}\]
For make constant current,
\[\large \bf r=0\]
\[\large \bf I=\frac{V}{R}=constant\]
OpenStudy (samigupta8):
Suno toh shi agr r=R b h toh b toh constant hi h current...

OpenStudy (samigupta8):
ur bhut bada b h toh b toh V/r reh jayega jo ki constant h
nhi kya.....
OpenStudy (mayankdevnani):
lekin usme humne battery ko change kiya naa
aur agar battery ko change kiya to,`r` be change hua
lekin current ki dusri value aa gayi na lekin humme voh original value chahiye
OpenStudy (mayankdevnani):
constant in the sense means definite value
OpenStudy (mayankdevnani):
agar load voh hi h, source voh hi h, to current constant rhega na
OpenStudy (samigupta8):
So u want to say that V/r iz not a constant

OpenStudy (mayankdevnani):
nope
OpenStudy (mayankdevnani):
because if we change V,r definitely changes
OpenStudy (samigupta8):
N evn V/2r is also not a constant quantity do u wanna say lyk dat....
OpenStudy (mayankdevnani):
battery ko change kiya , to internal resistance change hoga naa
OpenStudy (samigupta8):
Toh fir tum kya keh re ho ki definite value honi chahiye...wohi toh h yeh

arrey ! lekin hum baar baar battery ko change kr rahein h naa
OpenStudy (mayankdevnani):
aise to saare options correct h
OpenStudy (mayankdevnani):
thoda theoritically socho
OpenStudy (mayankdevnani):
r=R,current will be max and constant in this case

OpenStudy (samigupta8):
Haan
OpenStudy (mayankdevnani):
lekin humme har case main constant chaihye toh, r ko zero hona padega
OpenStudy (mayankdevnani):
load same and V same,to current will be same
OpenStudy (samigupta8):
Hadd h abhi toh kaha ki constant h ...fir kya keh re ho...
OpenStudy (mayankdevnani):
or in the other words,we are talking about
IDEAL BATTERY

OpenStudy (mayankdevnani):
thoda ek ek option pr socho aur phir mere comment pr dhyan do ki main kya kehna chah raha hoon
OpenStudy (mayankdevnani):
aise to main r>>R bhi le sakta hoon,usme bhi value constant aayegi
