# What is the maximum value of an ac voltage whose RMS value is 100 V?

The maximum value of an ac voltage is 141 V.

See the step by step solution

## Step 1: Listing the given quantities:

${\mathrm{V}}_{\mathrm{rms}}=100\mathrm{V}$

## Step 2: Understanding the concepts of rms value:

The value of maximum voltage can be found from its rms value using the corresponding relation.

## Step 3: Calculation of the maximum voltage:

To find maximum voltage:

$\begin{array}{rcl}{\mathrm{V}}_{\mathrm{max}}& =& \sqrt{2}{\mathrm{V}}_{\mathrm{rms}}\\ & =& \sqrt{2}×100\\ & =& 141\mathrm{V}\end{array}$

Hence, the maximum value of an ac voltage is data-custom-editor="chemistry" $141\mathrm{V}$.
