In the circuits shown below, the readings of the voltmeters and the ammeters will be:

Let V and I respresent, respectively, the readings of the voltmeter and ammetre shows in Fig. 6.34 , and let R_(V) and R_(V) be their equivalent resistances. Because of the resistances of the meters, the resistnce R is not simply equal to V//I . (a) When the circuit is connected as shows in Fig. 6.34 (a), shows that R = (V)/(I) - R_(A) Explain why the true resistance R is always less than V//I . (b) When the connections are as shows in Fig. 6.34 (b) Show that R = (V)/(I - (V//R_(V))) Explain why the true resistance R is always greater than V//I . (c ) Show that the power delivered to the resistor in part (i) is IV - I^(2) R_(A) and that in part (ii) is IV - (V^(2)//R_(V))

The value of resistance of an unknown resistor is calculated using the formula R = V//I where V and I are the readings of the voltmeter and the ammeter, respectivley. Consider the circuits below. The internal resistances of the voltmeter and the ammeter (R_V and R_G, respectively) are finite and nonzero. , Let R_(A) and R_(B) be the calculated values in the two cases A and B , respectively. If the resistance of voltmeter is R_(V) = 1k Omega and the percentage error in the measurement of R (the value of R is nearly 10 Omega )is

The reading of the A.C voltmeter in the network shown in figure is (where V is in volt)

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
