What to Focus On

  • Electric current is the rate of flow of electric charge through a conductor
  • Current can be steady (constant) or time-varying
  • Applications include everyday devices like torches, clocks, and electronic equipment

  • Current I = q/t for steady current, I = dq/dt for variable current
  • SI unit: ampere (A) = coulomb per second (C/s)
  • Current represents the number of charge carriers crossing per unit time

  • Free electrons are charge carriers in metals
  • Electric field causes drift motion of electrons
  • Random thermal motion exists even without applied field

Common Mistakes to Avoid

Current flows from negative to positive terminal outside the battery

In series combination, current divides in inverse ratio of resistances

Resistance of conductor decreases with increase in length
