The potential difference across the poles of a cell when no current is being taken from it is called the electromotive force (EMF) of the cell. I shall use the … WebFor a cell of emf 2 v, a balance is obtained for 50cm of the potentiometer wire. if the cell is shunted by a 2Ω resistor and the balance is obtained across 40cm of the wire, thye internal resistance of the cell is. A battery has am emf of 15 V and internal resistance of 1Ω.
IB Physics: Cells, EMF and Internal Resistance
WebDetermine the emf and internal resistance of an electrical cell Practical activities have been safety checked but not trialled by CLEAPSS. Users may need to adapt the risk assessment information to local circumstances. Practical 3: Determine the emf and internal resistance of an electrical cell Objective Safety WebAug 4, 2009 · The solar cell is modeled as a voltage (emf) source connected in series with an “internal” resistance. The emf of the cell may be determined by placing a voltmeter in parallel between the terminals of the open circuit. To determine the maximum current of the cell, place an ammeter in series with an otherwise short circuit. It is something borrowed for the bride
