What is the resistance of an ideal ammeter Why?
An ideal ammeter is an ammeter whose resistance is zero thus giving the user zero error in measurement. Practically there is no such conductor whose resistance is zero.
What is the resistance of an ideal ammeter?
For the ideal case, resistance of an ammeter is zero.
Why is the resistance of an ideal ammeter zero?
The resistance of an ideal ammeter should be zero. This is because an ammeter is connected in series in a circuit. This would decrease the amount of current flowing through the circuit. Hence, in order to avoid the change of current flowing in a circuit.
What is the value of resistance for ideal voltmeter and ideal ammeter?
Answer. The internal resistance of an ideal voltmeter is infinity and the internal resistance of an ideal ammeter is zero.
What is the resistance of an ideal resistance?
Ideal value of resistance is zero. This indicates that there has to be no power loss and zero voltage drop across the resistor.
What does ideal ammeter mean?
zero resistance
The current measured by ammeter will be accurate if there is no change in current of the circuit by the use of ammeter in series of circuit. It is possible if resistance is called ideal ammeter. Thus, an ideal ammeter has zero resistance.
Why is the resistance of an ideal voltmeter infinite?
A voltmeter is used to measure the potential difference across the two points of a circuit. For it, the voltmeter is connected in parallel across those two point. The potential difference measured by voltmeter will be accurate if no current is drawn by voltmeter. Thus, ideal voltmeter has infinite resistance.
Why the resistance of an ideal voltmeter is infinite?
For an ideal voltmeter no current should flow through it, all current should pass through the connected resistance so that its voltage can be accurately measured by voltmeter. It will be so if the resistance of voltmeter is infinite.
What is the value resistance of an ideal voltmeter?
The resistance of an ideal voltmeter should be infinite.
What should be the resistance of an ideal voltmeter and ammeter and why?
In an ideal situation, where the voltmeter is able to measure the actual potential difference across two points, there should be no current passing through it, and hence its resistance should be infinite. With infinite resistance, the ammeter would stop the flow of current in the circuit and hence won’t work at all.
Is it possible for an ammeter to have zero resistance?
Although, practically it is not possible to have zero resistance of an ammeter. If ammeter have zero resistance there will be no voltage drop across the ammeter and that time it will measure the most accurate value of current in circuit. Secondly, why is the resistance of an ideal voltmeter infinite?
What is the internal resistance of an ideal voltmeter and ammeter?
Answer: The internal resistance of an ideal voltmeter is infinity and the internal resistance of an ideal ammeter is zero. Ammeter is connected in series and voltmeter is connected in parallel with the electric appliance.
What is the difference between a voltmeter and an ammeter?
Just like voltmeters, ammeters tend to influence the amount of current in the circuits they’re connected to. However, unlike the ideal voltmeter, the ideal ammeter has zero internal resistance, so as to drop as little voltage as possible as current flows through it.
Why is a voltmeter placed in parallel to the circuit?
Ideal voltmeter has infinite resistance so no current will flow. This is why voltmeters are placed in parallel to the circuit, not in series. Ammeter is placed in series however and has low resistance.
