A short in a circuit can be identified by which of the following?

A short in a circuit occurs when there is an unintended path of low resistance that allows current to flow where it should not, usually bypassing the normal load. This results in a significant increase in current flow, often beyond the intended capacity of the circuit components.

Identifying a short is often related to observing high current flow because the excessive current can cause fuses to blow, circuit breakers to trip, or components to overheat and fail. The high current flow indicates that something is wrong in the circuit, helping technicians pinpoint the location and nature of the fault.

Low voltage flow, intermittent signals, and voltage spikes can indicate other issues in a circuit but do not directly signify a short. The presence of high current flow is a clear and immediate symptom of a short circuit condition.
