Kirchhoff's Laws & Measuring Instruments

The current passing through the battery in the given circuit, is:

Figure

Show answer and solution

Answer: (d)

  1. C and D are joined by a wire, and so are A and F. The network between B and E is: B–A 55, B–D 2.52.5, A–E 33, D–E 1.51.5, A–D 6 Ω6\ \Omega.
  2. 52.5=31.5\frac{5}{2.5} = \frac{3}{1.5}, so the bridge is balanced and 6 Ω6\ \Omega carries no current.
  3. RBE=(5+3)(2.5+1.5)8+4=83 ΩR_{BE} = \frac{(5+3)(2.5+1.5)}{8 + 4} = \frac{8}{3}\ \Omega
  4. Total =83+13+5.5+1.5=10 Ω= \frac{8}{3} + \frac{1}{3} + 5.5 + 1.5 = 10\ \Omega, so I=510I = \frac{5}{10}
  5. So the answer is (d) 0.5 A.
