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 WebAmmeter A 3 A_3 A 3 A, start subscript, 3, end subscript in series with the battery so it measures the current through it. Voltmeters measure the electric potential drop across components. The voltmeter is placed in parallel with the component of interest because components in parallel experience the same potential difference.
