Resistance is measured in ohms, symbolized by the Greek letter omega (). Learn more about other related concepts with the help of engaging video lessons by visiting BYJUS. The ohm is also the equivalent of a volt per ampere (V/A). Question 10. WebNew to Diablo III? Necessary cookies are absolutely essential for the website to function properly. The resistance formula is as follows: Resistance = voltage drop across a resistor/ current flowing through a resistor. The mathematical representation is as follows: = R A L. Resistance values are expressed in ohms (). The property of a conductor by virtue of which it opposes the flow of electric current through it is called resistance. While drifting free electrons collide with the ions and atoms of the conductor. To students of electronics, Ohms Law (E = IR) is as fundamentally important as Einsteins Relativity equation (E = mc) is to physicists.

Answer: Resistance is the property of a conductor, which determines the quantity of current that passes through it when a potential difference is applied across it. According to Newtons second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m . The cookie is used to store the user consent for the cookies in the category "Other. When an electric current flows through a bulb or any conductor, the conductor offers some obstruction to the current and this obstruction is known as electrical resistance and is denoted by R.Every material has an electrical resistance and this is the reason why conductors give out heat when current passes through it. A resistor is an electric component with a predetermined electrical resistance, like 1 ohm, 10 ohms 100 ohms 10000 ohms etc.. Resistance is the property of a conductor, which determines the quantity of current that passes through it when a potential difference is applied across it.

WebNCERT Syllabus for Class 10 2022-23 - National Council of Educational and Research Training releases prescribes the NCERT syllabus for Class 10. When a conductor is kept at a constant temperature, Ohms Law states that the current flowing through it is proportional to the voltage across it. It is represented by the uppercase letter R. The standard unit of resistance is ohm, sometimes written out as a word, and sometimes symbolized by the uppercase Greek letter omega. Specific resistance is defined as the resistance offered by a unit length and unit cross-section of the substance to a current when a voltage is applied to it.

The relationship between current, voltage and resistance is expressed by Ohms Law. Resistance is an important factor in electronic circuits, higher resistance makes the current flow more difficult, lower resistance makes the current flow less difficult. Batteries provide DC, which is generated from a chemical reaction inside of the battery.
