What does an ammmeter measure when it is placed between two cells?
An ammeter measures the total current flowing through the circuit when placed in series between two cells. It will measure the sum of the currents produced by both cells as they combine to flow through the circuit.
In what circuit are the cells wired up inside the car battery?
They are wired in series.
What happened to the voltage in the circuit as more dry cells were connected in the series?
The voltage increases in this case.
Why did Volta get an electric current when he connected the cells in a circuit?
Volta got an electric current when he connected the cells in a circuit because the cells produced a potential difference, or voltage, which created an electric field that allowed a flow of electrons to move through the circuit. This flow of electrons is what we call an electric current.
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
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 kind of current is produced by dry cells?
Simply, direct current (DC). The amount of current depends on the circuit it is used in.
Can 2 cells push electric current harder round a circuit?
No, cells do not push electric current harder around a circuit. Electric current is driven by the voltage difference between the cells. Adding more cells in series increases the voltage, which can result in more current flowing through the circuit, but the cells themselves do not push the current harder.
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
What happens to the light bulb when extra dry cells are added to the series circuit?
When extra dry cells are added to a series circuit containing a light bulb, the total voltage supplied to the circuit increases. This higher voltage can lead to an increase in the current flowing through the circuit, which may cause the light bulb to shine brighter. However, if the voltage exceeds the bulb's rated capacity, it could overheat and potentially burn out or become damaged. Therefore, caution should be taken when adding extra cells to avoid damaging the bulb.
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.
