Can a sound wave travel through plastic paper/bag? How do light, sound, and radio waves travel in space if space is a void and there is not any matter for the aforementioned to travel through? How far can sound waves travel? Simply: Sound is propagated in a gas (air) and space has no air.
With resistors many think carbon comps are required for true mojo, especially as plate loads. Others discount the mojo factor completely and go with metal film as the most stable and quiet in operation. While others split the difference and use carbon film for some of the mojo with better stability and quieter operation.
Resistors determine the flow of current in an electrical circuit. Where there is high resistance in a circuit the flow of current is small, where the resistance is low the flow of current is large. Resistance, voltage and current are connected in an electrical circuit by Ohm s Law.
