SpletSay there is a circuit with two 1.5 V cells and a 100 Ω resistor. If you connect two cells in series, then the total emf is 3 V. And the current will be 3 / 100 = 0.03 A (Using V = I R ): If you have the cells in parallel, then the total emf is 1.5 V, as the terminals of the cells are electrically at the same point. Splet04. okt. 2016 · (i) E = I (r + R) : to start with the emf of the cells are 1.5 V, so if you want to treat them as a single cell (which is maybe not a good idea) you should use 3V for their combined emf. (1.5 + 1.5) = 0.25 (r + 10) → r = 2 Ω so per one cell it is 1 Ω. Right? gneill said: Just look at the portion of the circuit that comprises the batteries.
