The voltage across a resistance R5 in the circuit of Fig. 3.10 is to be measured by a

voltmeter connected across it.

(a) If the voltmeter has an internal resistance (Rm) of 4750U, what is the measurement error?

(b) What value would the voltmeter internal resistance need to be in order to reduce

the measurement error to 1%?
