(a) Obtain the voltage Vo in the circuit of Fig. 2.127(a).

(b) Determine the voltage  measured when a voltmeter with 6-kΩ internal resistance is connected as shown in Fig. 2.127(b).

(c) The finite resistance of the meter introduces an error into the measurement. Calculate the percent error as

(d) Find the percent error if the internal resistance were 36 kΩ.
