A metal wire of radius 0.4 mm carries a current of 2 A. Find the magnitude of current density if the current is assumed to be uniformly distributed
Given: r = 0.4 mm = 0.4 × 10-3 m, I = 2 A To find: Current density (J) Formula: J = \(\frac{I}{A}\) Calculation: From formula, J = \(\frac{2}{3.142\times(0.4)^2\times10^{-6}}\) = 3.978 × 106 A/m2
