At a junction where two parallel branches meet, what happens to the currents from each branch?

• A. They cancel each other
• B. They flow independently without interacting
• C. They recombine to form the supply current
• D. They all continue to the next junction separately

Answer: (C)

Currents in parallel paths come together at the junction and add up to form the current that continues through the rest of the circuit. This follows Kirchhoff’s current law: the total current entering a junction must equal the total current leaving it. In a parallel network, the source current splits into the branches, and when the branch currents meet again at the junction, they recombine, so the current continuing along the main path is I1 + I2 (the sum of the branch currents). Currents don’t cancel here because they’re not flowing opposite along the same conductor; instead they merge to form the single supply current returning to the source.
