Slide_Wire_Experiment

Slide Wire Experiment Slide Wire Experiment (E-4) This experiment was engaged upon by measuring the internal resistance of three power sources and the electromotive force (emf). The potential difference between the terminals of such a source, when no current flows to en external circuit, is called an electromotive force, or emf source. The three power sources were a new 1.5V hobby battery an old 1.5V hobby battery, and a Daniel cell. A seat or source if electromotive foce may be any device that converts one type of energy (chemical, mechanical, light, etc.) into electrical energy. The work required to move 1 unit of positive charge from the negative to the positive terminal of a seat of emf, defines electromotive force in terms of work the seat of emf doe on electrical charges. All batteries, either new, old or Daniel cell, will give off some internal resistance. The internal resistance of the battery is due to its ability to hold back the total flow of charge from one electrode to another. The terminal voltage equals the emf when no current is drawn from the battery. This is determined by the chemical reactions in the battery.
