What is the rms value for 300mv peak to peak?

To find the root mean square (rms) value for a voltage given in peak-to-peak (Vpp), you need to divide the Vpp value by 2√2. In this case, the Vpp is 300mV, which is equivalent to 0.3V. Dividing 0.3V by 2√2 ≈ 2.828, the rms value is approximately 0.106 V.
