What is Understanding Electric Current and Resistance about?

Here are the key effects of internal resistance of a source on terminal potential difference and output power: - The internal resistance causes some of the electrical energy generated by the source to be dissipated as heat within the source itself. - For a given external load, the terminal potential difference (V) is less than the emf (E) of the source due to the IR drop across the internal resistance. V = E - Ir - The output power of the source is maximum when the external resistance equals the interna
