Solution to task 361 from Chertov´s for extramural stud
361. Coil and ammeter are connected in series and connected to a current source. A voltmeter with a resistance r = 4 kOhm is connected to the coil terminals. The ammeter shows I = 0.3 A, the voltmeter U = 120 V. Determine the coil resistance. How many percent will the error be if the resistance of the voltmeter is not taken into account when determining the resistance of the coil?
