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!
Three electric cells each have a voltage of 1.3Vwhat is the total voltage of the three cells if the cells are connected in parallel?
voltage is still 1.3V in parallel circuit, voltage stays the same but current adds up in series circuit, voltage adds up but current stays the same
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
What can you increase by adding more cells in a circuit?
amps
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.
What happened when volta connected the parts of his cells in a circuit?
when he connected the parts he got an electric current.
What happened to the voltage in the circuit as more dry cells were connected in the series?
The voltage increases in this case.
How many miliamperes are produced when 4 D cells are in series circuit?
The current in the circuit is(6,000)/(the resistance connected between the terminals of the D cells, in ohms)milliamperes

When you connect cells in series which two quantities are the same for all cells?
When battery cells are connected in series and a conducting circuit is connected between the terminals of the string, the current out of the positive terminal of each cell and the current into the negative terminal of each cell are all the same number.
What happened to the reading of ammeter and voltmeter if the number of dry cells are added in the circuit?
Assuming you add more cells in series, the voltage will increase. If you don't change the resistance of the circuit, this in turn will also increase the current.

voltage is still 1.3V in parallel circuit, voltage stays the same but current adds up in series circuit, voltage adds up but current stays the same
What is a Voltaic pile?
A voltaic pile is a set of individual Galvanic cells placed in series. The voltaic pile, invented by Alessandro Volta in 1800, was the first electric battery. Building on Galvani's 1780s discovery of how a circuit of two metals and a frog's leg can cause the frog's leg to respond, in 1791 Volta demonstrated that when two metals and brine-soaked cloth or cardboard are arranged in a circuit they produce an electric current. In 1800 Volta literally piled up several pairs of alternating copper (or silver) and zinc discs (electrodes) separated by cloth or cardboard soaked in brine (electrolyte) to increase the electrolyte conductivity. When the top and bottom contacts were connected by a wire, an electric current flowed through the voltaic pile and the connecting wire.
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 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 series connecte cells?
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.
Bulbs cells and switches are all circuit what?
