What else can I help you with?
The internal resistance of ammeter is?
The internal resistance of an ammeter is very low. This is necessary in order to minimize the impact of the ammeter on the circuit being measured, ensuring accurate readings of the current flowing through the circuit.
How do you measure the value of the amplitude of an electric current?
The value of the amplitude of an electric current is measured in amperes (A) using a tool called an ammeter. The ammeter is connected in series with the circuit to measure the flow of current. The reading on the ammeter displays the amplitude value of the current.
What instrument can be used to detect electron flow?
An ammeter is commonly used to detect electron flow in a circuit. The ammeter measures the amount of current (flow of electrons) passing through a specific point in the circuit.
Why is an ammeter called a tell tale?
An ammeter is sometimes called a "tell tale" because it is designed to provide a clear and immediate indication of the current flowing through a circuit. It "tells the tale" of the electrical current passing through the system by displaying the measurements on its dial or digital display.
A calibrated instrument that measures the amount of current present is?
an 'ammeter'
What is resistance of an ideal ammeter?
ideal ammeter has zero internal resistance
Why do ammeter resistanse is very small?
An ammeter with a large resistance will affect the circuit that it is trying to measure. The ideal ammeter (or any measuring tool) should not affect what is being measured.
Why the resistance of an ammeter is bery low?
0. An ammeter is placed in series with the circuit in question; if its' internal resistance is high, it will change the current flow, thus making the measurement meaningless. For the same reason an ideal voltage meter will have infinite resistance.
What should be the resistance of an ideal voltmeter?
infinity- so that all the voltage is measured across the component instead of losing some in voltometer circuitry
Is the input resitance of an ideal ammeter is low and the output resistance is high?
An ammeter does not have an 'output resistance'. It's important that its resistance is low so as not to add additional resistance into the circuit to which it is connected, otherwise the 'measured current' would be lower than the actual current.
How range of a ammeter is extended?
if we take resistance in parallel with ammeter then the range of ammeter will change.
The internal resistance of ammeter is?
The internal resistance of an ammeter is very low. This is necessary in order to minimize the impact of the ammeter on the circuit being measured, ensuring accurate readings of the current flowing through the circuit.
What are the parts of an ammeter?
ammeter real picture
What is a ammeter on Mars?
An Ammeter and a brick is a brick.
How do you check a dc ammeter?
a dc ammeter is a ammeter which has three pins and it works by two wires.
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)
If resistor is connected to 6 V battery the ammeter in the circuit reads 2A what is the value of the risistance?
Resistance of the load = voltage across the load/current through the loadWhich means that the resistance would be 3 ohms.(This is only true assuming that the load is purely resistive and the ammeter is ideal.)
