With cells connected in series, the total emf of the 'stack' is simply the sum of
the individual emf's of the individual cells.
-- Even if one cell is connected backwards in the string. Then its emf is considered
negative when the sum is being performed.
-- All of this is true only as long as there is no external connection between the
ends of the stack, you're measuring the emf on an 'open-circuit' basis with a
voltmeter, and the cells are not providing any current to an external circuit.
Once the series combination of cells is connected to an external circuit and begins
to produce current, the total emf at the terminals of the stack will decrease. It'll
depend on the magnitude of the current, and on the 'internal impedance' of each
cell. If the cells are not precisely identical and in identical states of charge, then
a calculation of the total emf is virtually impossible.

What function is used to calculate a value in a series of cells?
Many functions can be used to calculate a value. It depends on what exactly what you want to do. To total a range of cells you use the SUM function, one of the most commonly used functions. The following will add the values in all the cells from A2 to A20. =SUM(A2:A20)
What is the total voltage of a battery containing five 2 V cells connected in series?
Total voltage output of 5 2v cells connected in series would be 10v
How do you calculate total capacitance if connected in series?
reciprocal of the sum of the reciprocals.
What are the laws of series and parallel connection?
1.In series connection the total resistance is equal the total number of resistor that was connected in series 2.the current is constant in a series connection 3.in a series connection total voltage is equal the number of of volt per cells
A battery containing five 2V cells connected in series has a total voltage of?
10 volts. The formula to work that out is: quantity of cells*voltage of cells
Why can you not calculate the total impedance of two impedance in series?
You can. Give an example, and someone here will help.
A battery containing five 2 V cells connected in series has a total voltage of?
10v In series, just add them together.
What is the Excel formula to calculate the total of values in cells d7 through e20?
=SUM(D7:E20)
Which Excel function would be used to calculate the total points a student earned on a series of tests?
sum
If 3 1.5 V cells were connected in series what would the total voltage of the circuit be What about in Parallel?
4.5 volts in series; 1.5 volts in parallel.
When is it usually desirable to connect cells in series?
In electronics circuits current is common in series circuits and voltage is common across parallel circuits. LEDs in series draw less current, but require more voltage. Total power remains the same until multiple drivers are introduced in a parallel configuration.
How do you calculate the joint resistance in a series circuit with three resistances?
The resistance of a series circuit is simply the sum of the individual resistors.
