What is Resistance in Physics | Definition, Formula and Unit

We hope you all are well and your exam preparation is going well. We try to teach you something new with a new topic every day. Today also we have brought a very important topic What is Resistance in Physics. In which we will give you all the information. We are going to give complete information about what is resistance in physics, its definition, formula and unit. Friends, if you want to make physics easy in your preparation, then stay with us till the end and read the article written on What is Resistance in Physics carefully.

The opposition a material provides to the flow of electrical current is known as resistance. A component has one ohm of resistance when a single ampere of electricity flows through it and there is a single volt potential difference (voltage) across it. In a direct-current (DC) electrical circuit, the current is typically inversely proportional to the resistance while the applied voltage is maintained constant. The current is cut in half if the resistance doubles, and is doubled if the resistance halved.

What is Resistance in Physics

The quality of materials that permits the passage of electric current is referred to as resistance. The passage of stream is undoubtedly opposed by resistance. It is also symbolized by the capital letter R. The Greek uppercase letter omega Ω represents the unit of resistance, which is the ohm.

Resistance Formula

In the above we told you about What is Resistance in Physics. The amount of resistance an object offers to the flow of electric current is measured as its resistance. An electrical component called a resistor is utilized in circuits to supply a particular level of resistance. Resistance Formula is as follows-Read More...
