methode to solve circuit by kirchhoff's law

1. Accept unknown current in the given circuit and show their direction by arrow.

2. Choose any closed loop and find (the algebraic sum of voltage drops+the sum of e.m.fs in that closed loop.

3. Put the algebraic sum of voltage drops +the algebraic sum of e.m.fs equal to zero.

4. Write equation for as many closed loops as the number of unknown quantities.

5. If we get the value of current is negative sign that means the actual direction of this current is opposite to what we gave.
