Chapter 19, Problem 78GP

(choose chapter or problem)

The current through the \(4.0-k \Omega\) resistor in Fig. 19–77 is 3.10 mA. What is the terminal voltage \(V_{b a}\) of the “unknown”battery? (There are two answers. Why?)

\(4.0-k \Omega\)

\(V_{b a}\)

\(3.2 k \Omega\)

\(1.0 \Omega\)

\(8.0 \Omega\)

\(12.0 \mathrm{~V}\)
