None of … WebA Nonideal Ammeter. Unlike the idealized ammeter described in Section 25.4, any real ammeter has a nonzero resistance. (a) An ammeter with resistance $R_{A}$ is con...
WebThe reading of the ammeter for 500 Q is 9.82 mA. + 60 V Required information Consider the given circuit where = 7 mA. An ammeter with internal resistance R¡ is inserted between A and B to measure lo. Determine the reading of the ammeter for the following values of Ri NOTE: This is a multi-part question.
WebMar 22, 2024 · For accurate measurement, an ammeter must have very small resistance and very large current carrying capacity. For the ideal case, resistance of an ammeter is zero. Therefore, ammeter is made by connecting resistance in parallel with the coil of a galvanometer. This parallel resistance is called shunt. i need to feel good about myselfWebA battery of emf 12 V and negligible internal resistance is connected to a resistor of constant resistance 6?, an ideal ammeter and an ideal voltmeter.
