I'm new to electronics and I don't fully understand how short circuiting works. For example I have this battery LiMn 3000mAh, it states:
Nominal Voltage: 3.6V Standard Charge: 2A Continuous discharge current: 20A
First thing I don't understand is if I connect a wire between the positive and negative terminal, it would create a short circuit, correct? Can the battery blow up?
My goal is to simply make a hot wire, but I don't understand how will the wire 'determinate' how much current it needs or will it draw full 2A or even 20A from the battery?
If I use resistors, what's their purpose? to protect the battery from all the 'unused' electrons or to protect the wire?
What about taser gun? is it 'short circuiting' and what effect does it have on the power source?
