    [Bulb burnt out] means the bulb has been burnt because of too large current passing throught it. It will then be broken down and will not give out light any more.

    [Bulb short circuit] means the bulb has been by-passed, i.e. current doesn't flow through the bulb.

    blub burn out 咪姐係個燈泡燒左

    試問燒左仲form 唔form 到complete circuit?

    form 唔到complete circuit 係咪姐係short circuit?

    circuit 得兩種..(p.s. 本人CE lv..只聽過兩種..有錯請更正)

    一種係complete circuit...另一種係short circuit
