Unformatted text preview: Electric Field of Continuous Charge Distribution Divide the charge distribution into infinitesimal blocks. For 3D applications use charge per unit volume: = Q/V . For 2D applications use charge per unit area: = Q/A. For 1D applications use charge per unit length: = Q/L. Use Coulomb's law to calculate the electric field generated by each block. Use the superposition principle to calculate the resultant field from all blocks. Use symmetries whenever possible. z dE 2 dEi = k E= X i dqi ri ^ 2 ri dEi k Z dq r ^ r2 dE1 dq1 r1 r2 y dq2 x 14/1/2008 [tsl30 1/1 ...
