If an ammeter is placed in parallel with a a load on a circuit, the circuit can short out as the ammeter takes the place of the load, flowing freely through the meter. Never measure across a resister or other electronic load with an ammeter.
Remember, ammeters are used in series while voltmeters are used in parallel.
What else can I help you with?
Why ammeter cannot be connected in parallel?
An ammeter has low resistance (ideally no resistance) because it is placed in series with other circuit elements to detect how much current is flowing. If it is placed in parallel with a component it will short-circuit it. That is a bad thing.
Should an ammeter always be connected in parallel with a component?
No, an ammeter should never be placed in parallel with a component - it should always be placed in series, so that the current through the component is measured.If you place an ammeter in parallel with a component, you create a short circuit around the component. Depending on the rest of the circuit, you could damage the circuit, damage the ammeter, create a fire, etc. You certainly will affect the current through the component, and that is not what you want to accomplish.
How is ammeter and voltmeter attached to a circuit?
Ammeters are connected in series with the load under test. This requires the load be disconnected from the source, and the ammeter placed in circuit. Voltmeters are connected in parallel with the load under test. This does not require any circuit changes. Sorry, but WikiAnswers does not support illustrations.
What happed if ammeter is placed in parallel with the component?
Ammeters have a very low resistance, as to not interfere with the circuit they are measuring current in. As such if you connect a very low resistance in parallel, the component is essentially shorted. A great many ammeter fuses have been blown because of this.
How should an ammeter be placed in a circuit?
An ammeter should be placed in series, between the element you want to know the current of and the node the element was attached to before.
Where must a voltmeter be placed in a circuit?
One does NOT insert a voltmeter in a series cirtcuit...an ammeter can be inserted in series, though. A voltmeter is connected in parallel with the source voltage and low(ground) side.
Does it matter where you place an ammeter in a circuit?
Ammeters must always be placed in series in a circuit, otherwise they will not work babes :)
Is an ammeter found on a series or parallel circuit?
Series. An ammeter is used to measure current, and is connected in series! There are also clamp on ammeters that use a small current transformer that is placed around a wire in the current loop in question. A small amount of current will be induced on this wire which can be read by the meter. This is not exactly in series or in parallel, but it "steals" some power from the circuit to induce in the meter, and at the same time keeps the circuit intact.
How do you measure the current through a circuit without intercepting the supply?
Add an ammeter in parralel with the circuit. An ammeter in parallel with a circuit to be measured will not measure any current. In fact, placing an ammeter in parallel will cause a short. The ammeter must be placed in series with the circuit to be measured. It should be noted that this technique only allows for small magnitudes of current to be measured. One should not try to measure more than 10 amps using this method. However, this is not the goal of the question asked. I am not 100% sure what "intercepting the supply" means but I think the person asking the question means without breaking the circuit? In this case one could use a clamp on ammeter. There are several varieties that can measure low currents and there are those that can measure 100s of amps.
How does the current change in a circuit when the ammeter is placed in different spots?
the current value at any part of the circuit is dependent upon the circuit conditions and not the ammeter. The meter will simply allow you to read those currents, whatever they may be.
How an electric current is measured?
Electric current is typically measured using an ammeter, which is a device connected in series with the circuit. The ammeter measures the flow of electrons passing through a given point in the circuit, usually in units of amperes (A). The ammeter must be placed in series with the circuit to ensure that the current passes through it and can be accurately measured.
Why an ammeter is likely to burn out if connected in parallel combination?
ameter has a low resistance so if it is placed in parallel with the load then it will experiance voltage as much as the load and according to equation power=v2/r the power will be very high as high v or low r both favors for a high power dissipation . but on a series combination most of the voltage drop will be on load the ameter will not have a high power dissipation
