Question

In the derivation of the parallel combination result, the relation used for the currents is:

Options

• \[I = I_1 - I_2\]

• \[I_1 = I_2\]

• \[I = I_1 + I_2\]

• \[I = I_1 I_2\]

Answer 1

In a parallel combination, the current splits into branches, so the relation \[I = I_1 + I_2\] is used. The equality of currents \[I_1 = I_2\] is a feature of a series combination, not parallel.
