Title

Current, Voltage, Resistance
Quick revise

Current

  • Symbol I
  • Flow of electrons around the circuit
  • Measured in Amps (how fast the electrons travel around)

Voltage

  • Symbol V
  • Driving force that pushes electrons
  • Measured in Volts (electrical pressure)

This video explains about Current and Voltages

Resistance

  • Symbol R
  • Slows down the electrons
  • Measured in Ohms (resists the flow of the electrons)

circuit
