Question : 101 of 200

Marks: +1, -0

In a circuit, at a node, two currents

I _{1}

and

I _{2}

are entering the node and three current

I _{3}, I _{4}

and

I _{5}

are leaving the node. If

\KCL

is applied at the node, the correct equation will be:

Solution:

I _{1}

and

I _{2}

are entering the node
And current

I _{3}, I _{4}

, and

I _{5}

are leaving the node
From the above concept,

∑↙{i=0}↖N i_n=0

∴I _{1}+ I _{2}- I _{3}- I _{4}- I _{5}=0
