A wire of some length is bent in the form of a ring of diameter `2a` having self inductance `L`, then `L` will depend upon `a` as:

Text Solution

Verified by Experts

`phi=NBA`
`Li=N.(mu_(0)l)/(2a)xxpia^(2).N`
`"Now ", Nxx2pia=l`
`N=(l^(+))/(2pia)" "So,L=(l)/(2pia)xx(mu_(0)I)/(2a)xxpia^(2)`
`L oo a^(-1)`
