HI.... i wanted to do an extensive project on electricity and i thought of something. When i take a normal conduucting wire with a plastic insulation on it, and connect it in a circuit, does the insulation affect the current carrying capacity of the wire? i mean to say in one case if i apply a potential to it and suppose with the help of an ammeter find that lets say 10 amps of current is flowing through it....and in another case if i take the same conducting wire but this time without the insulation coating, will more current flow? like does the insulating material affect the current conducting capacity of the wire? i know we might get a shock if there was no insulation....but is this phenomenon possible? will more current flow? and if it will then how can i design an elaborate practical experiment...i mean for my project i need to take experimental readings and collect the numeric data....so how do i design the circuit?
