Final answer:
The available voltage ranges for devices can vary, from very low like 1 × 10^-3 V to extremely high like 10,000 V. For small electronics, typical ranges are 5V to 12V, with plug-in transformers often supporting this lower voltage range for devices different from the standard household supply.
Step-by-step explanation:
The voltage ranges that are available for various devices can vary widely. For small electronic devices such as calculators and cell phones, you may see voltages around 5V to 6V; for example, a calculator might use four 1.5V batteries for a total of 6V, while a cell phone typically recharges at around 5V. However, voltage requirements for different applications can extend much lower or much higher than this. For instance:
- The required voltage is 1 × 10-3 V. - This would be for very low-power applications.
- The required voltage is 10 V. - This is within the range for many small electronic devices.
- The required voltage is 1,000 V. - This would be a considerably higher voltage, potentially for industrial or special equipment.
- The required voltage is 10,000 V. - This is a very high voltage, typical for specialized industrial applications or power transmission.
From figures provided, we can see that the plug-in transformer has become common for electronic devices requiring voltages other than the standard residential supply of 120V AC or 220V AC, with most falling into the 3 to 12 V range. It is important to note that the household AC voltage typically alternates at a frequency of 60 Hz in the United States or 50 Hz in Europe, with potential differences indicating peak voltages that differ from the RMS voltage we use regularly.
