What causes the resistance in a circuit?

An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance. The relationship between resistance and wire length is proportional .

What do you mean by resistance class 10?

Resistance: Resistance is a property of conductor due to which it resists the flow of electric current through it. A component that is used to resist the flow of electric current in a circuit is called a resistor. In practical application, resistors are used to increase or decrease the electric current.

What causes resistors to have resistance?

A resistor like this is described as wire-wound. The number of copper turns controls the resistance very precisely: the more copper turns, and the thinner the copper, the higher the resistance. In smaller-value resistors, designed for lower-power circuits, the copper winding is replaced by a spiral pattern of carbon.

What is conductor resistance?

Conductor resistance is a property of a conductor at a specific temperature, and it is defined as the amount of opposition there is to the flow of electric current through a conducting medium.

What causes high resistance in a cable?

High resistance connections are typically caused by a defect in workmanship, with the failure to tighten connections the most common. The failure to align multiple conductors mated with a twist on connector such as a wire nut is another common cause.

What is the cause of resistance of a conductor Class 10?

Resistance is caused in a conductor by the free electrons. These free electrons collide with each other and with the ions and atoms that oppose their free movement. This obstruction is known as resistance.

What is resistance class 9?

Resistance is defined as an opposition to current flow. An electrical circuit must have resistance in it in order to change electrical energy to light, heat or movement. Resistance is an inherent opposition to the flow of electrons present in conductors.

What is the resistance of each resistor?

Resistor Locations The current going through each resistor will be the same, but the voltage going through each resistor is different. For example, say you have a 200 ohm, 50 ohm, and 25 ohm resistor placed in series. Your total resistance of your circuit is 200 + 50 + 25 = 275 ohms.

What is the cause of resistance of a conductor Class 12?

What are the 3 factors that affect resistance?

Resistance is the property of the material that restricts the flow of electrons. There are four factors affecting resistance which are Temperature, Length of wire, Area of the cross-section of the wire, and nature of the material.
