HELLO dear
The relation between resistance and other factors is given below :
R = pl/A ,
Where R - resistance , P - material's resistance (ohms ) , l - length , and A - cross sectional area ( m^2 ) .
According to the above relation , Resistance is directly proportional to length of the wire so as length increases by 0.2% , the resistance also increases by 0.2% .
If the original resistance is , then resistance will be 100.2
May this help you
