21. The circuit is the one shown at right ( from our Voltage divider article-which I've read ). 22. Voltage regulators are often used in lieu of passive voltage dividers when it is necessary to accommodate high or fluctuating load currents. 23. R3 and R4 then act as a voltage divider that makes Q1's base voltage negative and consequently turns off Q1. 24. The problem is that, in the solutions, my teacher used the same method as above, by using voltage dividers . 25. The necessary distribution of voltage along the series of dynodes is created by a voltage divider chain, as illustrated in the Figure. 26. Its collector voltage goes down and Q2 begins going cut-off, because the voltage divider now provides lower Q2 base voltage. 27. They have a capacitive voltage divider but also have a dual-winding transformer to couple the divided voltage to the metering circuit. 28. The two resistors form a voltage divider ; so, the additional resistor has to have low enough resistance to reach the low threshold. 29. Using the voltage divider ( R1, R2 and R3 ) allows choice of the arbitrary output voltage between U z and U in. 30. It does this by reducing the input voltage to a safe, measurable level with a precision voltage divider circuit within the probe body.
