【Product Description】
Each cement resistor in this set has a built-in protective cover.
【Overall Advantages to Users】
- Each cement resistor has a protective cover to avoid students from getting burned if they touch a resistor heated by an electric current.
- Students often select an incorrect cement resistor in their experiments because each resister has a similar appearance. To avoid this, color-coded resistance values for each type of cement resistor are printed on the protective cover.
