Abstract	Knowing the charge of the parton initiating a jet could be very useful both for testing different aspects of the Standard model and for searching signals of a beyond-the-standard-model physics. A weighted sum of the charges of a jet constituents can be used at the LHC experiments to distinguish among jets from partons with different charges. A few applications of the jet charge variable are presented here. The jet charge was used to distinguish jets initiated by $b$ quarks from those initiated by $\bar{b}$ quarks, for distinguishing between boosted hadronically decaying $W^+$ and $W^{-}$, and for distinguishing jets initiated by quarks from those initiated by gluons.
