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.
What else can I help you with?
Would thick wires tend to have the least amount of eletrical resistance?
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.
What is resistance expressed in?
Electrical resistance is measured in Ohms.
What is excessive electrical resistance?
High resistance means insulation
Is high electrical resistance good or bad?
electrical resistance is when something resists the electrical current .. eg rubber hope it helped
How does temperature affect resistance of a wire?
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
Compared to thin wires electrical resistance in thick wires are?
Lower in thick wires due to their larger cross-sectional area, which allows for more space for electrons to flow and reduces the resistance. Thicker wires also have less electrical resistance because they experience less heat loss, making them more efficient for carrying electrical currents over greater distances.
How does the size of the wire affect the electrical resistance?
The size of the wire directly affects the electrical resistance. Thicker wires have lower resistance compared to thinner wires, as there is more space for electrons to flow through, reducing the resistance. Conversely, thinner wires have higher resistance due to smaller pathways for electron movement.
What causes wires to get hot?
Wires get hot when electrical current flows through them, causing resistance in the wire. This resistance converts electrical energy into heat energy, making the wire hot.
Wires with high resistance change electrical energy into what?
Wires with high resistance change electrical energy into heat energy. This occurs due to the resistance in the wire hindering the flow of electrons, causing them to collide and generate heat.
What is the cause of voltage drop in electrical circuits?
Voltage drop in electrical circuits is caused by the resistance in the circuit components, such as wires, connections, and devices, which leads to a decrease in voltage as current flows through them.
Electric current flows in a wire which is opposed by what?
Electric current flowing in a wire is opposed by electrical resistance. This resistance is caused by factors such as the material of the wire, its length, and its cross-sectional area. It results in the conversion of electrical energy into heat.
What is the resistance of a connecting wire?
The resistance of a connecting wire can vary depending on its material, length, and thickness. In general, wires with a higher resistance will impede the flow of electrical current more than wires with lower resistance. It is important to consider the resistance of connecting wires in electrical circuits to ensure proper functionality.
What form of energy causes the wires in a toaster to give off heat and light?
Electrical energy heats the wires in a toaster to the point where they emit heat and light due to resistance in the wire. This resistance converts the electrical energy into thermal energy, resulting in the wires heating up and glowing.
What property causes wires and coils to become hot when electricity flows through them?
Yes, so electricity simply flow through them.Most Wires and Coils have resistance. This resistance opposes the flow of Current. This opposition creates Heat.
What causes electric wires to warm up?
Electric wires warm up due to the resistance they encounter when electricity flows through them. This resistance causes some of the electrical energy to be converted into heat, resulting in the wires becoming warm.
What are the wires leading to some wheel-speed sensors twisted?
They are twisted to improve resistance to electrical interference and the also help with improving voltage resistance.
Resistance in wires causes electrical energy to be converted to what energy form?
Resistance in wires causes electrical energy to be converted to heat energy. This is known as Joule heating, where the electrical energy is dissipated as heat due to collisions between electrons and atoms in the wire.
