A transformer has the ability to change an ac supply of 2kW,240V to 60V. a) what is the turns ratio of this transformer. b) how large is the output current if the transformer is 100% efficient. c) what will be the output current if there is a 10% power loss in the transformer

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
