 Whenever the resistance increases different things happen when voltage travels trough them. A higher resistance causes a voltage drop.
 This can be explained using Ohm's law 
 
- $V = I \cdot R$
- 
-The Voltage drop is Amperage ($I$) times the Resistance ($R$). So if you have a higher resistance or a lower Amperage you will get a voltage drop.

+The Voltage drop is Amperage $$I$$ times the Resistance $$R$$. So if you have a higher resistance or a lower Amperage you will get a voltage drop.
 Another side effect of having a higher resistance is that the resistor or trace will heat up more easily.
