In an ammeter 10 percent
WebDec 21, 2024 · The Ohm's law formula can be used to calculate the resistance as the quotient of the voltage and current. It can be written as: R = V/I. Where: R - resistance. V - voltage. I - Current. Resistance is expressed in ohms. Both the unit and the rule are named after Georg Ohm - the physicist and inventor of Ohm's law. 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. The resolution of the instrument is 0.1 A but the uncertainty in a reading is 0.05 A. Calculating percentage uncertainties

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). When an ammeter is placed in series with a circuit, it will increase the resistance of that circuit by an ... 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
