Questions
There is a current of 1.344 A in a copper wire whose area of cross-section normal to the length of the wire is 1 mm2. If the number of free electrons per cm3 is , then the drift velocity would be
detailed solution
Correct option is C
νd = inAe = 1.34410−6 × 1.6 ×10−19× 8.4 ×1022 =1.34410 × 1.6 × 8.4 = 0.01 cm/s=0.1 mm/sTalk to our academic expert!
