3. The circuit shown in Fig. 3 has two batteries of know emf 's 51 and 3 and ve resistors whose resistances are measured in the known unit of resistance R: R1 = R2 = R and R3 2 R; 2 3H and R5 = REE. Internal resistances of the batteries and resistances of all connecting wires are negligible. Find electric currents 11.. 12, 1'3, 1'4 and 15 owing through each respective resistor. How much power P is dissipated in the whole circuit in terms of emf's and R? Figure 3: Illustration for problem 3
