  1. Alternating Current Versus Direct Current By George Sereika

  2. DC Current • Direct current is the one way flow of electrical charge from a positive to a negative charge. • Batteries produce direct current. • Direct Current is different than alternating current because the charge only flows in one direction. • Thomas Edison is credited for promoting direct current.

  3. DC Examples • http://www.school-for-champions.com/science/dc.htm • DC Motor

  4. Alternating Current • Alternating Current is when charges flow back and forth from a source. • It is the way we receive our electricity (for our houses, businesses, etc.) • Nikola Tesla was a pioneer in the advancement of alternating current. • AC flows in the form of a sine wave, back and forth. • It is easier to transform voltages in AC. • The purpose of transformers is to convert AC voltages. • Transformers are extremely important to AC current, and our life.

  5. AC Examples • http://www.school-for-champions.com/science/ac.htm • how transformers work • Comparing AC vs. DC
