This is because electricity always flows through the path with the least resistance.

In the circuit with the bulb, there is more resistance, so the electric current does not flow through that path, and thus the bulb does not light up. (I tested it)

As electrons flow through the path with the least resistance, the circuit above will become a short circuit as there is no object to convert the electrons to light or heat energy.

Thus, electrons will not flow to the path with the bulb and as a result, the bulb will not light up as there are no electrons to be converted to light energy.]]> 2022-02-24 10:05:36 UTC https://padlet.com/mijiworkshop/bulbstopglowing/wish/2064291022 Elias Lee (5-2) https://padlet.com/mijiworkshop/bulbstopglowing/wish/2064310307 The diagonal wire is the wire that is added. It creates a short circuit and therefore although the bulb's circuit is not touched (It is still there). This is what Mrs Ng taught us in class.]]> 2022-02-24 10:20:34 UTC https://padlet.com/mijiworkshop/bulbstopglowing/wish/2064310307 Emmanuel Goh An Swee 5 Gen (5-2) gohemmanuel38 https://padlet.com/mijiworkshop/bulbstopglowing/wish/2064342889 The basics are that lightbulbs "give off" resistance which electricity does not like. As a result, electricity tries its best to bypass it, which it does by using the extra wire.]]> 2022-02-24 10:46:53 UTC https://padlet.com/mijiworkshop/bulbstopglowing/wish/2064342889 Wu Yiming 5-2 https://padlet.com/mijiworkshop/bulbstopglowing/wish/2064402339 1. The bulb lights up

2. 1 battery was disconnected

The electricity will flow through this new circuit instead of the one containing the lightbulb and will cause a short circuit, resulting in the lightbulb staying off.]]> 2022-02-24 12:29:50 UTC https://padlet.com/mijiworkshop/bulbstopglowing/wish/2064462365 Jacob Xu (5-2) mhmt2 https://padlet.com/mijiworkshop/bulbstopglowing/wish/2066076363 I added the additional wire between the battery and the bulb. The extra wire directed the current through itself and away from the bulb. Current travels through the path of least resistance and the path with the additional wire only has less resistance than the original path with the bulb. ]]> 2022-02-25 09:12:30 UTC https://padlet.com/mijiworkshop/bulbstopglowing/wish/2066076363 Matthias Ho (5-3) https://padlet.com/mijiworkshop/bulbstopglowing/wish/2066264907 The bulb does not light up as there is an extra wire with no components except the wire and little resistance. It would flow through that path and cause a short circuit, while electricity will not flow through the path with the bulb.]]> 2022-02-25 12:17:05 UTC https://padlet.com/mijiworkshop/bulbstopglowing/wish/2066264907 Wu Yikun 5-3/Fai wuyikun11 https://padlet.com/mijiworkshop/bulbstopglowing/wish/2066265607 Electrons will always take the path with less resistance. As the bulb has resistance, the electrons will choose the wire with nothing, thus no electricity flows through the bulb, and it will not light up.]]> 2022-02-25 12:17:46 UTC https://padlet.com/mijiworkshop/bulbstopglowing/wish/2066265607 Elias Lee (5-2) https://padlet.com/mijiworkshop/bulbstopglowing/wish/2067238524 Be careful of redundant wires!
