Problem 27.31

Which, if any, of these statements are true? (More than one may be true.) Explain. Assume the batteries are ideal. a. A battery supplies the energy to a circuit. b. A battery is a source of potential difference; the potential difference between the terminals of the battery is always the same. c. A battery is a source of current; the current leaving the battery is always the same.

Step-by-Step Solution:
Step 1 of 3

Rosanna Cheng PH 106 02.08.17 Pages 526-533 Reading Journal Prediction The chapter will continue to discuss electromotive force and terminal voltage. Notes 19.1 EMF and Terminal Voltage * A device that turns an energy into electric energy is a source of electromotive force. Potential difference between terminals is emf of source. The unit is volts. A battery has internal resistance. Terminal voltage is the difference of voltage between two points. Terminal voltage is current times resistance subtracted from electromotive force (Vab=EE-Ir). Usually, battery’s internal resistance is negligible and battery voltage is terminal voltage. Resistance is in ohms. 19.2 Resistors in Series and in Parallel * Series is when resistors are connected end
