This paper explores the fluctuations of net-charge in lead–lead (PbPb) collisions at a LHC energy, 
5.5 TeV using the variable 
. To generate data sets, the study uses the Monte Carlo-based heavy-ion event generator called A Multi-Phase Transport (AMPT) model in string-melting and default mode. The study reveals that the values of depend on the centrality and the pseudorapidity window (
). Additionally, the paper focuses on the dynamical net-charge fluctuations per unit entropy and the scaled value of as a function of . It also includes the strength of fluctuation for identified particle species. The results thus obtained from the AMPT model are compared with the available preliminary results by CMS collaboration at the LHC energy, 5.02 TeV. This work provides a baseline comparison with the experimental data and valuable insights into the AMPT model.
