Challenge: how low can you go?

• Light three LED's using the Uno in Tinkercad so that they appear to be all on at the same time using the least amount of current and no more than 3 kΩ worth of resistance.

• BASIC UNDERSTANDING

SESSION OVERVIEW: In this session we learnt about Parallel and Series Circuits alongside Source and Sink

• Parallel/Series Circuits

  • Parallel Circuits

    • A circuits with 2 or more paths for the current to flow through

    • The voltage is the same between both paths (lines) of the circuit

    • The sum of the currents in the paths(lines) is equal to the total current

  • Series Circuits

    • A circuit that has more than one resistor but only one path through which electricity flows

    • All paths in a series circuit are connected from end to end

    • A resistor in a series circuit uses some of the power from the cell

• Source/Sink

  • Source

    • The ability to output current

  • Sink

    • The ability to input current
