Recommended textbooks

  • University Physics with Modern Physics — Young & Freedman

    15th ed. Vol. 2 — electricity and magnetism section

  • Fundamentals of Physics — Halliday, Resnick & Walker

    11th ed. — strong on electromagnetic applications

How to pass PHY 121

  • Connect electricity topics to real circuits: every concept has a practical application
  • Draw circuit diagrams before applying Kirchhoff's laws — never solve blind
  • AC circuit analysis uses complex numbers from MTH — revise those in parallel
  • MIT OCW 8.02 Electricity and Magnetism lectures are free and excellent
