Web12 Mar 2024 · When the load is removed, the voltage goes back up, but over the lifetime of the cell, as the density of energy containing chemicals decreases, the voltage of the cell … Web13 Apr 2024 · Explanation: In the condition of the terminal voltage of a cell in an open circuit, it can be said that the terminal voltage will be equal to the emf of the cell. This is because the circuit is open, thus it comes with no drop across the internal resistance. Example 2.

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 … WebHowever, the voltage of a single-cell lithium battery is too small to provide a higher supply voltage, so a multi-cell battery is usually used in series (Wang, Polis, Yin, Chen, & Fu, 2012;Hsieh ... WebTerminal Potential Differnce & Lost Volts. If there was no internal resistance, the terminal p.d would be equal to the e.m.f. If a cell has internal resistance r, the terminal p.d is always lower than the e.m.f. If you have a load resistor R across the cell's terminals, then the terminal p.d V is equal to the p.d across the load resistor. In a ... hotters new shorts
