NCEA Electricity level 3 Exam Questions And Answers 100% Guaranteed Pass. Internal Resistance - AnswerThe internal resistance of a source is the loss of potential difference per unit current in the source when current passes through a source. It is the resistance encountered by a current as it passes through a battery. Gradient of current vs voltage graph. The internal resistance will increase as the products of the reaction in the cells build up. EMF - AnswerThe potential difference acros...
