Transcript of "Electric current and Voltage"

  1. 1. In electric circuit, the energy carriers are free electrons. COULOMB – basic unit of electric charge ***To produce 1 coulomb of electric charge, 6.3 x 10 by 18 electrons are required.
  2. 2. 1 a = 1C/ sec = 0.3 A/sec x sec / 6.3 x 10^18 C = 0.048 A C= It = (0.048 C/sec) (1 sec) = 0.048 C
  3. 3. AC ( alternating current) DC (Direct current)
  4. 4. A battery produces direct current in a circuit because the terminals have the same opposite charges.
  5. 5. A kind of current in household circuits wherein there is a continuous back and forth movement of electrons in the circuit.
  6. 6.  Direct Current  DC  Provided by batteries  Alternating Current  AC  Provided by power companies
