    See the electrical circuit shown in this figure. Which of the following equations is a correct equation for it?

    A) \[{{M}_{1}}\times {{M}_{2}}\]

    B) \[{{Z}_{1}}{{Z}_{2}}\]

    C) \[{{Z}_{1}}\]

    D) \[{{M}_{1}}\]

    Correct Answer: A

    Solution :

    Key Idea Apply Kirchhoffs second law also called loop rule. The algebraic sum of the changes in potential in complete transversal of a mesh (closed loop) is zero. ie, \[2\pi x{{10}^{6}}Hz\] Here \[\frac{\omega (M-2m)}{M+2m}\] If there are n meshes in a circuit, the number of independent equations in accordance with loop law will be (n-1).
