Using chiral EFT one is able to construct current operators at the many-body level. As a result of this, it is guaranteed that the current operators can be evaluated consistently with the appropriate nuclear wave functions, obtained as well from chiral interactions. This consistency is a key advantage of the EFT framework. In this talk, we discuss the development of electroweak currents in few-nucleon systems and their applications to electromagnetic form factors as well as electroweak transitions in light nuclei. In particular we look at triton and helium-3.
