Master Electrician Exam 2025 – 400 Free Practice Questions to Pass the Exam

Question: 1 / 400

What is one potential consequence of a short circuit?

Increased voltage

Circuit interruption

Excessive current flow

A short circuit occurs when there is an unintended path of low resistance that allows current to flow freely, bypassing the intended circuit load. This typically results in a significant increase in current flow because the current takes the path of least resistance. As a result, excessive current can cause a variety of issues, including overheating of wires, damage to components, and even fire hazards.

Understanding the consequences of excessive current flow is critical for electricians, as it underscores the importance of proper circuit design and protection mechanisms, such as circuit breakers and fuses, which are designed to interrupt current flow in dangerous situations to prevent damage or injury.
