What Causes High Resistance In A Circuit

What Causes High Resistance In A Circuit Resistance opposition to current flow in a circuit Connection anomalies pose resistance problems in our motor circuits and if they are not identified and corrected they can have deleterious effects Normal things that affect circuit resistance are conductor resistance length of the wire size of the wire in circular mils

Flowing in a circuit is affected by the resistance of that circuit Each component in a circuit has a resistance Can you answer these questions based on the video What happens to the current The resistance in a circuit depends on several factors such as the material the circuit is made of the length and thickness of the material and the temperature of the material Generally materials with high resistivity longer length and smaller cross sectional area will have higher resistance

A high resistance connection HRC is a hazard that results from loose or poor connections in traditional electrical accessories and switchgear which can cause heat to develop capable of starting a fire High resistance is a fundamental and common parameter in circuit design enabling engineers to achieve specific performance characteristics and functions Whether it is voltage division current limiting noise filtering or thermal sensing high resistance components play a vital role in ensuring the proper operation of electronic systems

According to IEEE a high resistance R connection in an induction motor electrical circuit results in localized overheating and supply voltage unbalance which leads to a decreased efficiency and reliability and an increased fire hazard in the electrical distribution system and motor What are the factors affecting resistance The resistance varies directly proportional to the length of the conductor If the conductor is longer there will be more resistance This is because resistance is caused by the collision between electrons and atoms present in the conductor

Resistance is an important factor in electronic circuits higher resistance makes the current flow more difficult lower resistance makes the current flow less difficult Depends how you are conducting the test If using a 3 pin plug lead then corrosion in socket Otherwise as you say a high resistance joint what is the MOST likely cause of a high resistance MEASUREMENT when testing continuity of cpc Also a bad contact with your probes for the above
