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.
