    If the gadge of the wire is bigger it offers more resistance to current. Overalll circuit impedance decreases. Therefore current increases.

    That depends on the resistance of each wire and the load applied. Total circuit resistance=R , One wire= R1, Other wire=R2 Load=R3 --> Total resistance R= R1+R2+R3
    With current being voltage divided by resistance : the lower the total R is, the higher the current will rise - if the power supply allows for that.
    And with one common-to-all current passing through three resistors, the voltages over each of them will add up to the totally supplied voltage. Using a 12 Volt DC supply that means that a specific load will see for instance 0.4 volt over wire 1, 0.6 volt over wire 2, and therefore only 11 volt over the load itself.

    If the wire gauge is increaded(made larger) the wire is able to carry more current ---LESS resistance to the current not more. If you substitute a larger pipe for a smaller one, the total volume of material moved increases,, same principal
