When current returns to the source without flowing through the load, it is referred to as a(n) ?

When current returns to the source without flowing through the load, it is referred to as a(n) ?

• A. Closed
• B. Incomplete
• C. Open
• D. Short

Answer: (D)

A short circuit describes a situation where current finds a very low-resistance path back to the source that bypasses the load. That bypass is what makes the current return without delivering energy to the intended component, so the circuit effectively “shorts” around the load. This is precisely what happens when current goes straight back to the source instead of through the load, leading to a large, potentially dangerous current that can trip fuses or breakers and cause overheating. In contrast, a closed circuit means current flows along the intended path and through the load, delivering energy. An open (or incomplete) path breaks the circuit so current cannot complete a loop at all.
