The sum of the branch currents in a parallel circuit is equa

The sum of the branch currents in a parallel circuit is equal to the of the circuit.

what is in blanket I should write?

Solution

The sum of branch currents in a parallel circuit is equals to total current supplied in the circuit This is also called Kirchoffs current law.

Let a circuit has three branches having three currents I_1,I₂,I_3.

Total current is I.

so from KCL       I =   I₁ + I₂ + I₃
