In an ammeter 10 percent
WebAgain, to examine the loading effect of the ammeter in Figure 1.3 (b), we must develop an equivalent circuit model for our ammeter. As in the case of the voltmeter, the ammeter can be represented by its equivalent resistance, R am. Thus, with the ammeter inserted into our circuit, the equivalent circuit is given in Figure 1.4. Again Web7. Using the same circuit, repeat the procedure above for an ammeter reading of 1.0 A. …

WebOne way to measure the internal resistance of an ammeter is the circuit below. The decade box R2 is set to zero, and R1 is chosen for an approximate full scale reading for the ammeter. R2 is then adjusted to halve this reading, so its resistance equals that of the ammeter. r i for Leybold multimeter on 10 V scale = 34,000 ohms WebThe accuracy of the ammeter KAis the ratio of the current when the meter is in the circuit, IW, to the current with the meter out of the circuit, 10. Equation (14-5) is the mathematical representation for solving for the accuracy of the ammeter (KA).
