What is AC current

a current that periodically reverses direction and changes its magnitude continuously with time 

100

What is DC current

an electric current is one-directional flow of electric charge.

AC currents Examples

  • Battery-powered objects

  • Home electronics

  • Electrochemical cells

DC currents examples

  • Efficient long-distance transmission without significant power loss

  • Creating rotation in devices

300

pros

  • Travels well over large distances

  • Greater efficiency

300

pros

  • Direct current can be stored in batteries.

  • Lower voltage – safer

  • Frequency 0 (no oscillation)

400

cons

  • Higher voltage – not as safe

  • Magnitude varies with time

400

cons

  • Voltage of DC cannot travel very far as it begins to lose energy.

  • Less efficiency
