If I1 in the given circuit is 1 A, what will be the current I2 in the 2^nd circuit?

 

The correct answer is option 1):(1 A)

Concept:

Reciprocity Theorem: In any passive linear bilateral network, if a single voltage source ‘V’ in the branch AB produces the current response ‘I’ in the branch CD, then the removal of the voltage source from the branch AB and its insertion in the branch CD will produce same current ‘I’ in the branch AB.

In the reciprocity theorem, if the position of excitation and responses are interchanged, then their ratio remains the same.

\(\frac{{{V_1}}}{{{I_1}}} = \frac{{{V_2}}}{{{I_2}}}\)

Calculation:

Given

Circuit 1: V₁ = 14 V, I₁ = 1 A Circuit 2: V₂ = 14 V, I₂ = ?

\(\frac{{{V_1}}}{{{I_1}}} = \frac{{{V_2}}}{{{I_2}}}\)

I2 =  1
