In VOM's, what is the function of voltage multiplier resistors?

• A. To increase current
• B. To ensure accuracy
• C. In the voltage scales
• D. To ground the unit

Answer: (C)

The role of voltage multiplier resistors in a volt/ohm meter (VOM) is critical when it comes to adjusting the voltage range that the meter can measure. By dividing voltage across resistors in the voltage multiplier circuit, these resistors effectively allow the meter to handle a wider range of input voltages without damaging the internal components. This means that when selecting a specific voltage scale on the VOM, the voltage multiplier resistors help determine how much of the input voltage is presented to the measuring circuit. Because of their arrangement in the multiplier, they can create different voltage outputs based on the selected scale, facilitating accurate readings over a comprehensive range of voltages. Understanding this function helps in recognizing the importance of voltage scaling in VOMs, which is essential for precise measurements in various electronic applications.
