The amplitude of the charge oscillating in a circuit decreases exponentially as \(Q={Q}_{0}{e}^{-Rt/2L}\), where \({\mathrm{Q}}_{0}\) is the charge at \(t=0\mathrm{s}\). The time at which charge amplitude decreases to \(0.50{Q}_{0}\) is nearly :
[Given that \(\mathrm{R}=1.5\Omega ,\mathrm{L}=12\mathrm{mH},\ln (2)=0.693\) ]
