b) Apply the principles of circuit theory to the circuit illustrated in Figure 2 with constant sources, to explain the operation of each one by calculating the current I (using Thevenin or Superposition theorem). \( R_{1}=2 \Omega, r=3 \Omega, R_{2}=5 \Omega \) and assume \( E_{1}=5 \mathrm{~V} \) and \( E_{2}=15 \mathrm{~V} \).
