Question

Four resistances are connected in a circuit as shown in the given figure. The electric current flowing through $4 \,ohm$ and $6\, ohm$ resistance, respectively, are

• A. 2 A and 4 A
• B. 1 A and 2 A
• C. 1 A and 1 A
• D. 2 A and 2 A

Answer 1

Answer: (D)

Equivalent resistance $=\frac{4 \times 4}{4+4}+\frac{6 \times 6}{6+6}=5\,\,ohm .$
So the current in the circuit $=\frac{20}{5}=4$ ampere.
Hence, the current flowing thro ugh each resistance $=2$ ampere.
