Estimate the average drift speed of conduction electrons in a copper wire of cross-sectional area 1. @PhysicsMasterAcademy

Uploaded January 2026 | Updated September 2026, 3 weeks ago

Estimate the average drift speed of conduction electrons in a copper wire of cross-sectional area 1.0x10-7m2 carrying a current of 1.5A. Assume the each copper atom contributes roughly one condition electron. The density of copper is 9.0X10^3 kg/m^3, and its atomic mass is 63.5 u. (b) Compare the drift speed obtained above with. (i) thermal speeds os copper atoms at ordinary temperature, (ii) speed of propagation of electric field along the conductor which causes the drift motion. | class 12 physics chapter-current electricity solution by ujwal Kumar physics master | physics master academy is best coaching for all physics students. | ujwal kumar
