FINDING THE INTERNAL RESISTANCE OF A POWER PACK AIM Design and Carry Out an experiment to determine the EMF and Internal Resistance of a standard laboratory power pack. THEORY This information was taken from the Collins advanced science Physics textbook, the Cambridge Advance Science Physics 1 textbook and from notes taken in class. E.M.F or Electro Motive Force is the opposite of potential difference, in that; it is the situation where a voltage is gaining energy. This seems unlikely, but it is required in order to allow an electric circuit to function. An electric current is a flow of electric charge, the charge flows around the circuit, transferring some of its energy to areas of resistance along the way (resistors, filament lamps, buzzers). At some point along the way the energy must be initially supplied, otherwise the whole process couldn't function. At the beginning of the process the power supply provides the...
