The more resistance in a circuit the less current. One form of Ohms Law is I=E/R. That means current (I) equals voltage (E)divided by resistance (R). For instance, 12 volts, 1 ohm=12 amps. If you double the resistance (R) to 2 ohms and have 12 volts, your current drops to 6 Amps. If you quadruple the resistance to 4 Ohms, your current drops to 3 amps.
Smaller wire won't make a properly designed circuit's CB pop unless it melts and shorts together.
