Solving a problem in physics section 67 point 50 electr
50. In the circuit (see the figure) ε1 = ε2 = ε3, R1 = 20 Ohms, R2 = 12 Ohms, the voltage drop U2 at the resistance R2 is 6 B. Neglecting the internal resistance of the EMF sources, determine: 1) current strength in all sections chains; 2) resistance R3.
