Determine the magnitudes and directions of the currents in
Chapter 19, Problem 28(choose chapter or problem)
Determine the magnitudes and directions of the currents in each resistor shown in Fig. 19–56. The batteries have emfs of \(\mathscr E_1=9.0~\mathrm V\) and \(\mathscr E_2=12.0~\mathrm V\) and the resistors have values of \(R_1=25~ \Omega,~R_2=68~ \Omega\), and \(R_3=35~ \Omega\).
\((a)\) Ignore internal resistance of the batteries.
\((b)\) Assume each battery has internal resistance \(r=1.0~ \Omega\).
