Webb2. In the absence of electric field, the free electrons in the metal have random motions. During motion, they collide with positive ions of the metal again and again and after each collision, their direction changes. So, there is no net flow of charge carries in a particular direction and hence no current flows. 3. WebbVarieties of Questions are Given: In the Current Electricity PDF questions for NEET, varieties of questions are provided for students to solve. By practising varieties of questions, students can automatically reduce the amount of silly mistakes made in the chapter Current Electricity PDF.
Webb10 jan. 2024 · Ques. The average drift speed of conduction electrons in a copper wire of cross-sectional area is 1.0 × 10 -7 m2 carrying a current of 1.5 A. Assume that the density of conduction electrons is 9 × 1028 m-3. (All India 2014) Ans. Given : Current I=1.5 A, Cross-sectional area A = 1×10 -7 m 2. WebbDrift velocity is very small, it is of the order of 10–4m/s which is negligible as compared to thermal speed of e–s at room temperature ( 105 m/s) The drift velocity is given by. where, J = current density. e = electronic charge = 1.6 × 10–19 C. n = the number of free electrons per unit volume.

Webb10 juli 2024 · Just as mechanical energy used to overcome friction is covered into heat, in the same way, electrical energy is converted into heat energy when an electric current flows through a resistance wire. The heat produced in a conductor, when a current flows through it is found to depend directly on (a) strength of current (b) resistance of the …
