Question

A current of 1.34a exist in a copper wire of 1mm^2 . Assuming each copper atom contributes one free electron. Calculate the drift speed of the free electrons in the wire . The density of copper wire is 8990 kg/m^3 and atomic mass is 63.5g

Answer 1

Answer:

a current of 130 power in power of one metre sq ring is copper a pond contribution of re election calculate the drift speed of the free electrons of the wire the destination of the copper wire is 98 108 kg of water per 3 and mass is 63.5
