p = vi
I = 0.1818

v=IR
R=1210

P DIRECT PROSUN BY I SQAR R
R2= 756.25

R1-R2 = 453.87

Carboxylic: hi i had used the value of current as 0.18 only and then used the formula V=IR to calculate the resistance

Carboxylic: so in first case my answer is 1222.22 ohms and second case the current came out to be 0.11 so my resistance was 2000

Carboxylic: so is my answer correct as well

Carboxylic: and one more thing we just had to mention whether the change occurred or not and we just had to calculate the new values

Carboxylic: please confirm

mrjk: may be your R2 second resistance is value is wrong...

mrjk: my ans is right I think...but I am not confirm. ..

Carboxylic: no i have checked my R2 it's correct

Carboxylic: will my answer be marked wrong in boards if i took the values of current in decimals and calculated my answer using current in decimals

mrjk: ok...
