An ammeter is placed in series with a circuit in order to measure the current. If it has any appreciable resistance, inserting the ammeter will increase the normal resistance of the circuit and reduce the value of the current flowing through it. The ammeter will, therefore, give an inaccurate reading (under-read). So the ammeter must have a very low resistance so that it has the minimum effect on the normal resistance of the circuit being tested. Ideally, the ammeter should have zero resistance but, of course, this is impossible.

Why should the connecting wires in a bulb be of low resistance?
This is to avoid energy losses in the connecting wires.
What are some examples of items with low conductivity?
Thermal resistance: diamond Electrical resistance: copper Optical resistance: quartz

How does the loading effect of an ammeter in a low resistance circuit compare to the loading effect in a high resistance circuit?
The voltmeter has an internal resistance, which should be as high as possible. As this resistance draws current from the circuit under test, it will affect circuit operation. This is more pronounced in a high impedance circuit because the current drawn flows through higher resistances.
Does plastic have low resistance?
yes, it does have low resistance
Is graphite a high resistance or low resistance of electricity?
Graphite is low resistance of electricity...
Which has the thickest filament - a high-resistance or a low-resistance bulb?
A low resistance bulb has a thicker filament.
Good conductors have a high resistance or low?
Good conductors have low resistance
What wire connection better high or low resistance?
Usually low resistance is better.
Why should the connecting wires in a bulb be of low resistance?
This is to avoid energy losses in the connecting wires.
What has a low resistance?
Silver and gold both have low resistances. Superconductors have zero electrical resistance. People with acquired immune deficiency syndrome (AIDS) also have low resistance to infection. Many women have a low resistance to my charming and magnetic personality.
Does gold have a high or low resistance?
Gold has a low resistance, which means it is a good conductor of electricity. This property makes it useful in various electrical applications where low resistance is needed for efficient conduction of electricity.
If a multimeter reads zero on the ohm scale is this high or low resistance?
zero is low resistance
What happens when you have low resistance?
When you have low resistance, it means that it is easier for you to go. If there is not as much as resistance with something holding you back,?æthen you can go faster, and not be held back.
What type of resistance do conductors have?
Conductors have a (low) Electrical resistance.
Do meters usually have a high or low internal resistance?
It depends on the application. Voltmeters have a high internal resistance, while ammeters have a low internal resistance.
