Two equal resistances R\(_{1}\) = R\(_{2}\)= R are connected with a 30 \(\Omega\) resistor and a battery of terminal voltage V. The currents in the two branches are 2.25 A and 1.5 A as shown in the figure. Then, what will happen? Please explain the answer in brief.
R\(_{2}\)= 15\(\Omega\)
R\(_{2}\) = 30\(\Omega\)

The circuit shown in the figure contains two diodes D1 and D2, each with a forward resistance of 50\(\Omega\) and infinite backward resistance. If the battery voltage is 6 V, then how can do come to know the resistance of the current (in amperes) through the 100\(\Omega\)? Please help me to solve this problem.
