Resistance Of Ideal Ammeter. The shunt is nothing more than a resistor with a very low resistance. This parallel resistance is called shunt.

As i understand, ideally an ammeter will have zero resistance as it is connected in series with the circuit and so there will be no potential difference across the device. I have recently determined the internal resistance of an ammeter in an. The ammeter and voltmeter readings are medium view solution > assertion Web an ammeter ideally should have zero resistance if it is not to have absolutely any effect on current being measured. Web an ideal ammeter is an ammeter whose resistance is zero thus giving the user zero error in measurement. Web an ammeter is used to measure the current in a circuit. Web resistance of an ideal voltmeter is infinite and that of an ammeter is zero. Nearly all of the current will flow thought the shunt. And which in turn reduces the current and hence we face error in the current. Hence, an ideal ammeter should have zero resistance.
0 0 similar questions an ideal ammeter (zero resistance) and ideal voltmeter (infinite resistance) are connected as shown in fig. Note that this ideal resistance value is exactly opposite as that of a voltmeter. Therefore, ammeter is made by connecting resistance in parallel with the coil of a galvanometer. The shunt is nothing more than a resistor with a very low resistance. It is connected in series with the circuit to avoid division of current, but ‘when placed in series with the circuit, it increases the resistance and decreases the current being measured by it. However, in reality there will be a very small internal resistance associated with an ammeter. For the ideal case, resistance of an ammeter is zero. And which in turn reduces the current and hence we face error in the current. Web 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. Web resistance of an ideal ammeter is zero because ammeter is connected in series to measure the current to ensure that there must not be any volatage drop because of the internal resistance of ammeter it is ideally taken as zero. The ammeter and voltmeter readings are medium view solution > assertion
