What happens if an ammeter is connected in parallel and voltmeter connected in series in a circuit?
The voltmeter will register the volts, the ammeter will either explode or blow a fuse since it has a very low resistance and is designed to be used in series to measure the current flowing through it.
Why the positive terminal of an ammeter is connected to the positive terminal of battery?
The proper polarity has to be adhered to so as to make the meter's needle deflection move in the correct direction. The wrong polarity will deflect the needle in the opposite direction and pin the needle against the needle stop on the left side of the meter's scale. This could un-calibrate the ammeter and the readings would not be accurate if this happens.
What happens if you charge a 12 volt battery backwards?
You cannot charge it connected backwards. You will destroy the battery.
What happens when an ammeter is connected in parallel with a circuit?
SMOKE!!! Yiii-haaaa! An ammeter is always as low a resistance as possible. That way, the current that you measure in a circuit using the meter will be the same as if the meter were not there. So putting an ammeter in parallel with a circuit means that you just short circuited the circuit you were intending to measure. Poof! There goes your ammeter!An ammeter has a very low internal resistance. So, if it is connected in parallel with a load, it will short-out that load. The resulting high current flowing through the ammeter may severely damage the meter (and possible harm the user), although most are fitted with fuses to protect them.
What happens when a battery is connected wrong on a 1997 mercury villager?
you can blow fuses or the battery Possible computer damage.
What happens when a battery is connected to a alternating current source?
this action is very dangerous and should not be considered.
What happens when an ammeter is connected wrong?
Ammeters have a low impedance, so if they are incorrectly connected in parallel to your load instead of in series, more current will flow through the circuit and the ammeter will almost act like a short. There is potential to burn our the ammeter.
What happens to an ammeter when there is a break in a circuit?
An ammeter reads the current that is flowing through a branch of a circuit. If there is a break within that same branch of the circuit, current will not be able to flow through that branch of the circuit as it forms an incomplete loop, so the ammeter will read 0 A of current. If there is a break in a circuit in a branch that is not connected to the ammeter however, the ammeter will give a higher reading of the current. This is assuming that the break in the other branch does not short out the branch with the ammeter attached, and that the circuit can still form a complete loop without that branch.
What happens in a battery's negative terminal when it is not part of a circuit?
When a battery's negative terminal is not connected to a circuit, it accumulates excess electrons, creating a negative charge. This creates a potential difference between the positive and negative terminals, which is the driving force for the flow of electric current when the battery is connected to a circuit.
What happens when one 12 volt battery connected parrellel to 2 batteries of 12 V at the same time?
4V
What happens when the car battery connectors connect together?
When a car battery in connected to itself (i.e. You connect jumper cables onto a battery and then connect the other two connectors to each other), you create a continual circuit with the battery and nothing else. A similar effect is when you hold a 9 Volt battery to your tongue and you feel a small but continual "zap". Imagine this effect, but much greater. Sparks will appear when the connectors are first connected. Warning: Do not do this. This will damage your car battery. The only reason you should connect a car battery through jumper cables is to connect it to another car's battery in order to "jump" a car.
What do centromeres hold together?
DNA duplicates chromosomes that are connected at the centromere. They are usually connected through the kinetochore-microtubule which happens during the process of mitosis.
