What is the self-inductance of a solenoid of length 40cm, area of cross - section `20cm^(2)` and total number of turns is 800 ?

Text Solution

Verified by Experts

Given :
I = 40cm = 0.4m
`A=20cm^(2)=20xx10^(-4)m^(2)`
N = 800, L = ?
`Lequiv(mu_(0)N^(2)A)/(l)=(4pixx10^(-7)xx(800)^(2)xx20xx10^(-4))/(0.4)`
`L=4.02xx10^(-5)H`
