The battery in Figure P31.95 has internal resistance (R_{text {batt }}=13.0 Omega) and maintains an emf (mathscr{E}=20.0

Question:

The battery in Figure P31.95 has internal resistance \(R_{\text {batt }}=13.0 \Omega\) and maintains an emf \(\mathscr{E}=20.0 \mathrm{~V}\). What is the resistance \(R\) of the resistor connected in series with the battery if the current through the circuit is \(0.100 \mathrm{~A}\) ?
