Electromotive force e m f of cell E 1 = 4 V. Resistance, R 1 = 2 Ω. Resistance, R 1 = 8 Ω. Step2: Finding the equivalent current in the circuit. We know that: I e q = E e f f R e q. Where, I e q = equivalent current, E e f f = effective e m f, R e q = equivalent resistance. According to Kirchhoff ...
A cell E1 of emf 6V and internal resistance 2Ω is connected with ...
WebIn this case we can assume that the internal resistances are zero. So, we can simply apply the Kirchoff Voltage Law in the loop. V eff = E 1 - E 2. (Given r 1 = r 2 = 0) Given the EMF of one cell is E 1 = 1.25 V. The EMF of the other cell is E 2 = 0.75 V. V eff = E 1 - E 2 = 1.25 V - 0.75 V = 0.5V. So, the correct option is 0.5 V. WebAutomobile battery systems are 2.1 volts per cell; a "12 V" battery is 6 cells, or 12.6 V; a "24 V" battery is 12 ... a ratio because the cgs unit of voltage is inconveniently small and one volt in this definition is approximately the emf of a Daniell cell, the standard source of voltage in the telegraph systems of the day ... nowosad and company port hardy
