HideShow resource information

What is current?

  • flow of electron
  • current will only flow if there is a voltage
  • current is measured in amps, A

What is voltage?

  • The force that pushes the current around. This means if you increase the voltage you increase the current
  • battery
  • measured in volts, V

What is Resistance

  • Resistance is anything that slows down or opposes the flow of electrons.
  • This means if you increase the resistance the current decreases (or more voltage is needed to keep the same current flowing)
  • measured in ohms, Ω
