Determine the resistance `r` if an ammeter shows a current of `I = 5 A` and a voltmeter `100 V`. The internal resistance of the voltmeter is `R=2,500Omega`

The circuit shown here is used to measure resitance R. An ammeter shows a current of 2A and a voltmeter of a potential difference of 120 V. what is the resitance R if the internal resistance of the voltmeter is R_(v) = 3000 Omega ? How large will the error in measuring R be, if the resistance of the voltmeter is assumed to be infinitely large?

The actual value of resistance R, shown in the figure is 30 Omega . This is measured in an experiment as shown using the standard formula R = (V)/(I) , where V and I are the readings of the voltmeter and ammeter, respectively. If the measured value of R is 5% less, then the internal resistance of the voltmeter is
