WebTheory The purpose of this lab is to be able to demonstrate Kirchhoff’s first and second rules for electrical circuits. Kirchhoff’s Rules are used instead of Ohm’s Law when the Ohm’s laws start having limitations due to circuits being more complicated. Kirchhoff’s first rule states that the sum of all currents entering a junction must equal the sum of all currents leaving … WebAmmeter. The ammeter measures electric current. It may be calibrated in amperes, milliamperes, or microamperes. In order to measure current, the ammeter must be placed in series with the circuit to be tested (as shown in below Figure 1).

WebI was wondering how can I find internal resistance of multimeter, in both voltmeter and ammeter capabilities? I thought it was termed as input impedance but when I looked up the specs of multimeter, in example, Agilent 34410A Digital Multimeter, it said load impedance was 1 MΩ ± 2%, in parallel with <150 pF in True RMS AC Voltage, which did not make any … WebThis also applies to digital instruments. An ammeter records currents to 0.1 A. A current of 0.36 A would be displayed as 0.4 A, and a current of 0.44 A would also be displayed as 0.4 A.
