SUMMARY
The drift velocity of electrons in a conductor can be calculated using the formula v = i/(NqA), where i is the current, N is the electron concentration, q is the charge of an electron, and A is the cross-sectional area. For a conductor with a cross-sectional area of 8x10^-6 m^2 carrying a current of 8A and an electron concentration of 5x10^28 electrons/m^3, the drift velocity can be determined by substituting these values into the equation. This method provides a clear step-by-step approach to solving drift velocity problems in electrical circuits.
