What you'll learn

Each question helps you build key knowledge and skills.

  • 1V = I x R links voltage, current and resistance.
  • 2In series circuits, current is the same everywhere and voltages add up.
  • 3In parallel circuits, voltage is the same across each branch and currents add up.
  • 4Filament lamps have resistance that increases with temperature; diodes only let current flow one way.
