A 1.5 mH inductor in LC circuit stores a maximum energy of `17 mu` J. What is the peak current ?

Text Solution

Verified by Experts

Here, `L = 1.5 mH = 1.5 xx 10^(-3) H, E_(0) = 17 mu J = 17 xx 10^(-6) J, I_(0) = ?`
From `E_(0) = (1)/(2) LI_(0)^(2) , I_(0) = sqrt((2 E_(0))/(L)) = sqrt((2 xx 17 xx 10^(-6))/(15 xx 10^(-3))) = sqrt((34)/(15) xx 10^(-2)) = 0.15 A`
