When talking about resistance in an electrical circuit, it refers to the measure of the opposition to the current flow. It is measured in ohms, and it is normally measured to indicate the condition of a specific component or circuit. But what is meant by “resistance” in short circuits?
An Overview of Short Circuits
What is a short circuit?
The Spruce has a good primer on this topic. Basically, a short circuit happens when electrical flow travels through at a shorter distance than is present with the established writing.
Electricity is supposed to return to ground, and in a circuit that is functioning well, the current will flow through the wiring circuit to the service panel and then through the utility wires.
However, if the connections are broken or loose, the electricity flow may leak and flow through a shorter pathway. Hot wires with a live current could touch a neutral wire, and this could cause crackling or smoke. Short circuits can be dangerous and could cause a fire or electrical shock.
How do you know if you have a short circuit?
The most frequent signs of a short circuit is when a circuit breaker trips and causes the circuit to shut down.
How does resistance work?
The higher the resistance, the lower the electrical current flow. If it is abnormally high resistance, conductors could be damaged with burning or corrosion. Conductors generally give off some heat, but if it’s overheating, that is usually because of the resistance.
If the resistance is low, the current flow will be higher. This could be caused by damaged insulators that are wet or overheated.
Understanding how electricity works can be tricky. There are lots of things to consider: high voltage, the voltage source, the resistance path, open circuits, resistance to the flow, infinite resistance, how these affect the rest of the circuit.
If you think you have a short circuit and you need it to be fixed, don’t try to do it yourself. Knowing how resistance works and determining the best option for repair is important. An experienced electrician can do it safely.
