I must say that electricity is hard to grasp conceptually. Just when it makes sense, you think hard about it and it all becomes confusing.
When someone says electricity takes the path of least resistance, it never made much sense. Consider you have a light bulb and one of the wires connecting to it is bare and the bulb is on. If I touch the bare wire, I will get a shock and it will travel through my body to the ground. I can understand this if I cut the bare wire and connected myself in series with the bulb. There is no where for the electricity to go. But when I touch the wire, I am in parallel with the bulb. The bare wire has less resistance so shouldn't the electricity bypass my body and go straight to the ground terminal? There's less resistance to get there as opposed to going through my body which is very resistant.
What is so special about ground (the floor) that electricity goes to it. How can it possibly complete the circuit?
