The formula to calculate the Effective Voltage (Veff) is:
\[ Veff = \frac{Vp}{\sqrt{2}} \]
Where:
Effective voltage, also known as root mean square (RMS) voltage, is a measure of the equivalent DC voltage that would produce the same power dissipation in a resistive load as the actual AC voltage. It is a crucial parameter in electrical engineering for analyzing AC circuits.
Let's say the peak voltage (Vp) is 10 volts. Using the formula:
\[ Veff = \frac{10}{\sqrt{2}} \approx 7.07 \, \text{volts} \]
So, the effective voltage (Veff) is approximately 7.07 volts.
Definition: The effective value (or RMS value) of an AC voltage is the equivalent DC voltage that delivers the same power.
Formula: \( V_{eff} = \sqrt{\frac{1}{T} \int_0^T v(t)^2 , dt} \)
Example: \( V_{eff} = \sqrt{\frac{1}{10} \int_0^{10} (5 \sin(t))^2 , dt} \)
