Product description

6. Reel and ammeter connected in series and connected to a power supply. The terminals of the coil is connected to a voltmeter resistance r = 4 ohms. The ammeter shows the strength of the current I = 0,3 A voltmeter - Voltage U = 120 V. To determine the resistance R of the coil. Determine the relative error ε, which will be allowed in the measurement of resistance, if we neglect the power of the current flowing through the voltmeter.
