Choose all that apply. A changing magnetic field will always induce a voltage. As current through an inductor decreases, the inductance remains constant. For an LR circuit, as R increases, & decreases. Transformers can simultaneously decrease voltage & decrease current. Generators transform electrical energy (electricity) into kinetic energy.
