  1. Current and Voltage

  2. Current Flow rate of electricity Current flows from + to – Measured in Amps – 1 Amp = 1 Coulomb per second Actually electrons flow in the opposite direction Many electrons make up one coulomb of charge All the current flow rate around a circuit is the same. (Current in branches adds up to equal the total current (exception! = capacitors)

  3. 1 Volt is 1 Joule per Coulomb It is the energy transfer to or from a coulomb of charge Electro-motive force (EMF) The work done on (energy transferred to) a coulomb of charge by a battery or power supply Voltage Potential Difference The energy level difference between two places P = VI Voltage and current The greater the potential difference between two places the higher the current. The ratio voltage:current is resistance ( V = IR )
