Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFDigital voltmeters:
- A digital voltmeter (DVM) is an electronic device used to measure the voltage in electrical circuits.
- Unlike analog voltmeters, which use a pointer on a scale to indicate the voltage level, digital voltmeters display the voltage value directly in numerical form on a digital screen.
- Digital voltmeters work by converting the electrical voltage being measured into a digital signal, which is then processed by the device's internal circuitry and displayed as a numerical value on the screen.
- They offer high accuracy, resolution, and often have additional features such as auto-ranging
Voltage and pressure: Digital voltmeters are specifically designed to measure voltage. Pressure, on the other hand, typically refers to mechanical force applied to a surface and is not directly measured by voltmeters.
Here, option 1 is correct.
