Walker, Halliday & Resnick — Circuits: Problem 13

13 In Fig. 27-14, assume that \(\mathcal{E} = 13.2 \text{ V}\), \(r = 100 \ \Omega\), \(R_1 = 250 \ \Omega\), and \(R_2 = 300 \ \Omega\). If the voltmeter resistance \(R_V\) is \(5.0 \text{ k}\Omega\), what percent error does it introduce into the measurement of the potential difference across \(R_1\)? Ignore the presence of the ammeter.
