A resistor with color bands blue- red-green-yellow-gold has a length of 5cm. If the material is made out of carbon, how much material (in terms of volume) is present in this resistor? If you are going to change the carbon to glass, how much smaller would it be? (Note, take the lower limit of the final resistance and the resistivity constant of carbon and glass)
