11. In this case, the voltage divider R1-R2 compensates the voltage variations to some extent. 12. The two resistors R C2 and R E form another voltage divider that determines the high threshold. 13. The conventional voltage divider ( Kelvin divider ) uses a tapped string of resistors connected in series. 14. In a Colpitts VFO, the voltage divider contains the variable capacitor ( either C1 or C2 ). 15. Now, the two resistors R C1 and R E form a voltage divider that determines the low threshold. 16. The R 1-R 2 voltage divider conveys this change to the Q2 base voltage and it begins conducting. 17. The two resistors R 1 and R 2 act only as a " pure " attenuator ( voltage divider ). 18. These parasitic capacitances act as voltage dividers with the circuit's storage capacitors reducing the output voltage still further. 19. Capacitors C1 and C2 form a voltage divider that determines the amount of feedback voltage applied to the transistor input. 20. The standard voltage divider circuit discussed above faces a drawback AC feedback caused by resistor R E reduces the gain.
