3 identical dry cells each
of e. m.f. 1.6 V are connected in a series to a resistor of 11.4 ohms. A current of 0.32A flows in the circuit. Determine:
a) the total em. f of the cell
b) the internal resistance of each cell.​

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
