electrical resistence is occur in conductor due to over flow of current,in conductor
AnswerResistance is not due to the 'flow of current'. It exists whether current is flowing or not! Resistance is determined by the type of material and its physical dimensions. Resistance depends upon the resistivity (which is also affected by temperature) of the material, and the length and cross-sectional area of that material.
The property of materials to oppose the flow of current is called as resistance. Electrical resistance occurs due to the collision of electrons to the lattice ions.
Flow of electrons collide with ions due to which a kind of resistance occurs.
Resistance occurs in wires when electrons collide with atoms. This slows down the flow of electrons, which means that the current will decrease.
Yes, the resistance is directly proportional to length of wire and inversely proportional Area, hence when Length of wire increases the resistance also increases and when Area increases the resistance decreases. This means a thick wire has least amount of Electrical resistance.
Electrical resistance is measured in Ohms.
High resistance means insulation
electrical resistance is when something resists the electrical current .. eg rubber hope it helped
If you are asking if a hot wire has a greater resistance than a cold wire then the answer I would say is yes. Cold wires have always had less resistance than hot wires
The electrical resistance in thick wires is less than thin.
Heat.
io
They are twisted to improve resistance to electrical interference and the also help with improving voltage resistance.
Resistance, which is measured in ohms. long wires and heat are the main cause of resistance increases.
Use the continuity test facility , I have information on my website and links for testing and inspection http://www.rbgrant.co.uk
Electrical resistance can be determined by the equation that defines resistance - Ohm's Law. Just divide the voltage across a resistor, by the current passing through it.
Most resistors convert electrical energy into thermal energy, which is often called heat.
corroded/dirty connections
All ordinary conductors have some resistance to the flow of electrical current. When current flows through resistance power is produced and dissipated as heat.
A short circuit is when the current in a circuit flows directly from the live/phase conductor to the neutral conductor without passing through a load. This is dangerous because the amount of current in a circuit is determined by the resistance/impedance (assuming constant voltage). The resistance of the conductor is very low and this allows large amounts of current to flow which should operate the circuits protective device (fuse). In the absence of a protective device the current will cause the conuctor toheat up first producing fumes from burning insulation and eventually seting on fire.
Primarily to keep and and all moisture away from the electrical connections. Water is a conductor of electricity ... if it comes into contact with electrical wires, it will cause a direct short and possible fire.
