across the ends of a wire of
resistance lohm when a
Current of 3 A passes through it
grade 10th science ​

Answer 1

Answer:

Science NCERT Grade 10, Chapter 12, Electricity is all about the flow of electric current in the electric circuits and its related concepts. The chapter lays emphasis on the understanding of electric current and its direction of flow in circuits. Additionally, the SI unit of electric charge and an electric current is mentioned in the chapter. Also, a schematic diagram of an electric circuit comprising a cell, electric bulb, ammeter and plug key is shown. Explanation of the flow of charges inside the wire is given in the chapter. The concepts such as electric potential and potential difference along with their definitions and SI units are explained using circuit diagrams and numerical. Some symbols of commonly used components in the electric circuits are shown in a tabulated form. A detailed explanation of the Ohm's law in addition to the mathematical expression of the relationship between potential difference and current is provided. The term Ohm is defined in the chapter, Electricity. Further, the factors on which the resistance of a conductor depends are mentioned and explained using activities. Electrical resistivity of the material of conductor is defined. The two methods of joining the resistors together are discussed with proper electric circuits:

Answer 2

Solutions:-

given data :- I = 1 ohm , R = 3A

potential difference is V

formula for potential difference is

V = I × R

V = 1 × 3

V = 3 volt

Hence potential difference is 3 volt.

I hope it helps you......
