Wire size consideration.

[Sunny55]

Hi, i am working on a circuit that is used to measure the battery's voltage. The battery is rated at 12V,100Ah. My question is can i use normal size jumper wires or do i need to go for thicker wires? What is the difference if i use thicker wires for the circuit compared to normal wires? Would thicker wires damage the components due to its wire width?(Just assuming).

I know its silly but for safety i would want to use the correct wire.

Thanks.

Thick conductors are needed for high current. If you're simply measuring the voltage of the battery, I expect you are not drawing very much current, so you can use very thin wire if you like, or thick if you like. However, that is a large battery - so I'm assuming you're doing something fairly high current with it. Just make sure the high current load is attached via separate wires from the low current voltage measuring setup. Hope this makes sense!
