Net-charge fluctuations in ultrarelativistic heavy-ion collisions are studied, in terms of the variable $\nu_{[+-,dyn]}$, analysing data from pp, p-Pb and Pb-Pb collisions at $\sqrt{s}_{NN}$ = 5.02 TeV and Xe-Xe collisions at $\sqrt{s}_{NN}$ = 5.44 TeV from the ALICE experiment at LHC. Data from various collision systems provide an opportunity to study the dependence of $\nu_{[+-,dyn]}$ on the system size. The effect of the kinematic acceptance has also been looked into by plotting the $\nu_{[+-,dyn]}$ against the collision centrality in various p$_{T}$ windows. In order to check whether the net charge fluctuations are influenced by the decay of hadronic resonances, experimental findings are compared with the Monte Carlo model HIJING. Moreover, the presence of collectivity has also been examined by analysing the AMPT data sets from the two modes of the model$-$with string melting and rescattering, as well as the EPOS model tuned for the LHC physics.
