Kirchhoff's Laws & Measuring Instruments

Figure

In the given circuit, the current in each resistance is:

Show answer and solution

Answer: (a)

  1. In every loop the top and bottom cells point the same way, so going round the loop one is crossed +→−+ \to - and the other −→+- \to +.
  2. Net emf in each loop =2−2=0= 2 - 2 = 0.
  3. With zero current everywhere, KVL holds in every loop, and the solution is unique.
  4. So the answer is (a) 0 A.
