Задача 30384.

Resistor and ammeter are connected in series and connected to a current source. In parallel resistor connected voltmeter impedance of 4 ohms. Indications 0.3 A ammeter, voltmeter 120 V. Determine the relative error that can be tolerated in the determination of the resistance of the resistor, if we neglect the voltage drop across the ammeter.

Detailed solution shorthand terms, formulas and laws used in the decision, the withdrawal of the calculation formula and the response.
