Chapter 18: Direct-Current Circuits

Chapter 18: Direct-Current Circuits. Homework assignment : 9,16,28,41,50. What is emf? . A current is maintained in a closed circuit by a source of emf. The term emf was originally an abbreviation for electromotive force but emf is NOT really a force, so the long term is discouraged.
