Question

Which mathematical form represents Kirchhoff's Current Law using an algebraic sum of currents?

Options

• \[\sum E=\sum IR\]

• \[\sum V=0\]

• \[\sum_{i=1}^{n} I_i=1\]

• \[\sum_{i=1}^{n} I_i=0\]

Answer 1

With a consistent sign convention, the algebraic sum of currents at a junction is zero. This is the mathematical form of KCL.
