Understanding the Root Mean Square (RMS) value is crucial in analyzing alternating current (AC) voltages. The RMS value provides a representation of the effective voltage in an AC circuit, offering a more accurate measure than the standard mean.
Formula: The RMS value is calculated using the formula: RMS = Vm / √2, where Vm is the maximum voltage amplitude.
How to Use:
- Input the AC voltage in the designated field.
- Click the “Calculate” button.
- The calculated RMS value will be displayed in the result field.
Example: Suppose you have an AC voltage with a maximum amplitude (Vm) of 10 volts. Enter 10 in the input field, click “Calculate,” and you’ll get the RMS value.
