What will happen if you connect the ammeter in parallel with the component?

All the current would go through the ammeter. The whole purpose for making a measurement with an ammeter is to determine current draw through a component or circuit. If the ammeter takes all the current away from the device under test, the reading would be meaningless. Also, since the ammeter would present pretty much a dead short to the power supply, blown fuses or toasted components usually result.

What is going to happen in 2015?
nothing will happen by natalia
Does don't count on it mean no?
It means, do not assume it is gonna happen
Do you believe thing happen for a reason?
i do believe that most of the things happen for a reason...

When was Nothing's Going to Happen created?
Nothing's Going to Happen was created on 2002-10-01.
What happen if you change the position of ammeter in the circuit in parallel and series?
-- In a series circuit, no matter where you install the ammeter, it will always read the same current. -- In a parallel circuit, the ammeter may read a different current when it's moved to a different parallel branch.
What happen when a ammeter is placed in parallel with the circuit?
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 will happen to voltage in a parallel circuit?
In a parallel circuit the voltage across each component is the same.
What will happen if ammeter is put across a resistance in a circuit?
Maybe blow the fuse or burn out the wiring. An ammeter has an extremely low resistance. connecting it across the resistance causes the resulting parallel resistance to be slightly lower than the resistance of the ammeter 1/Rt = 1/R + 1/R(ammeter)
What will happen if the reading of ammeter a2 after passing through 30 ohm resistance if reading of a1 is 3A after passing through 20 ohm resistance if both are parallel to each other?
5 A
What happen when ammeter connected in parallel?
an ideal ammeter has zero or negligible resistance when this is connected in series no effective resistance would be added in the circuit so that the value of curret that we get is exactly of the circuit only. but when the ammeter is connected in parllel as it has zero resistance , the resistor to which it is connected in parllel gets shorted and due to his the effective resistance of the circuit is changed and so the effective current ... due to this the w=value measured by the ammeter would be different (incresed due to dec. in effective resistance)
What will happen to the ammeter reading if the resistance is increased?
The current decreases due to I=V/R. The ammeter reading will decrease as R is increased.
What will happen to an ammeter reading if the resistors are connected in parallel?
You would be drawing more current. It would be the same as adding more load to the circuit in a vehicle, say more lights. The lights would just be seen as more load (a resistive load in the case of incandescent lights). Add more lights (resistors) and more current is needed. The ammeter would indicate a higher current draw.
What would happen if a voltmeter were substituted for an ammeter?
Smoke. Since a voltmeter is in parallel with the load it is right across the source voltage. Putting the amp meter across the line with its low resistance it will act like a fuse, hence the smoke. Newer solid state testers are usually smarter that the operators. They have built in circuitry which sense the wrong settings you are using and shut the tester off with a "beep" to let you know that you are doing something wrong.
Fuse should be connected to a circuit by parallel?
Fuse is a circuit element which disconnects the electrical current from the mains"supply" feeding the load when a condition of fault "short circuit " occurs. one behaviour of electric current that it flows undivided in circuit elements connected in series and is divided when flows in circuit elements connected in parallel. so in order to protect a circuit fuse MUST be connected in series to cut/disconnect the faulty current in a safe/short time. if u connect a fuse in parallel to a component then u will be shorting that component and the component will not function ;because the fuse is a thin wire with a negligible resistance and electrical current flows in the most easy "less resistive" component. besides a short circuit will happen immediatly because u connectthe supply to the neutral! hope that helps.
When an AC 5A and dc Current of 5A applied simultaneously to the circuit then what it happen?
A DC ammeter will read zero
What would happen if the earth would be parallel to the sun?
Two spheres cannot be parallel - only lines can be parallel.
