Carbon film resistors. A resistor is a passive component used to control current in a circuit. The coloured bands on the resistors represents the voltage and tolerance of each resistor. Each colour stands for a number, three bands show the resistors value in ohms and the fourth shows its tolerance. The resister at top is 4.70k ohms, the middle one is 2.2k ohms, and the one at the bottom is 470k ohms.
