Why do you build solar cells in both parallel series and series configurations?
You put them in series to get more voltage, and in parallel to get more current (amperage).
When two identical cells are connected either in series or parallel across a 2 ohm resistor they send the same current through it calculate the internal resistance of each cell?
as the given cells have the same current flowing in through them (current flowing through the cells connected in series is equal to the current flowing when connected in parallel ) equate the formula's of cells connected in series and cells connected in parallel.thus by equating we get the value of the internal resistor as 2 ohms.
What will happened if cells were connected in parallel connection but in opposite polarities?
You would get a high circulating current through both cells, possibly enough to do significant damage to both the cells and to you, depending on the capacity of the cells. Technically, they would actually be connected in series, not parallel!
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.
Are the car battery cells connected in a parallel or in a series?
Sereies, with each cell about 2.2volts
What advantage is there in arranging the batteries in series and in parallel?
A series connection of [five] cells gives you [five] times the voltage of a single cell.A parallel connection of [five] cells gives you the same voltage, but [five] times thebattery life, of a single cell.
Are car battery cells connected in series or in parallel?
Battery cells are conneted in series. Each cell of a 12v battery averages 2.1v when charged. SERIES 2-4-6-8 and so on
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 can two 4v lamps be lit up by two 2v cells?
-- Connect the cells in series. The two terminals of their series combination present a potential difference of 4 volts. -- Connect both lamps in parallel between the terminals of the series-connected cells.
When cells are connected in parallel then?
putting cells in series gives you a higher voltage but at the same current rating. putting cells in parallel gives you the same voltage but at a higher current rating. series parallel can give you both..
When two cells with the same voltage are connected in a series circuit what happens to the voltage?
There is addition of voltage. Dry cells have 1.5 volts irrespective of there size. if the cells are added as same polarity in series it will add if are parallel then voltage remains same
How do you calculate total emf in parallel connected cells?
When connecting cells in parallel, it is important that they are all of the same type. The total e.m.f. of cells connected in parallel is equal the the e.m.f. of an individual cell. So, if each cell has an e.m.f. of, say, 1.5 V, then it doesn't matter whether you have one cell or a hundred cells, the e.m.f. of the resulting battery will also be 1.5 V.
