If the peak voltage of a system is 230VAC of a sine wave, what will be its RMS voltage?How to convert mm to cm with a formulaA 100-Watt incandescent light bulb is approximately 1% efficient. a. What is the power of the light emitted by such a bulb? b. How much heat (thermal en...
When you want to know how much the electricity is costing you, you use watts. When you are specifying equipment loads, fuses, and wiring sizes you use the VA, or the rms voltage and rms amperage. This is because VA considers the peak of both current and voltage, without taking into acc...
How much power is produced if a voltage of 12 V is applied to a circuit with a resistance of 24 Omega? A capacitor is connected across an AC generator whose frequency is 47 Hz and has a peak voltage 148 V. The rms current in the circuit is 50 A. a) What is the capacitance of ...
Since it is the ratio of two voltages, they can be measured as peak-to-peak or RMS and with the same units. Reference voltage 1 mV. dBμV or dBuV (decibel microvolt, amplitude ratio) — absolute voltage in decibels relative to one microvolt, used to measure the signal strength in RF...
If you wanted the FFT output in units of dBm, you would want to use the FFT Amp Spectrum (Volts RMS) function instead. This function outputs an array of voltage values (assuming the input is an array of voltage values) that represent the voltage in each frequency bin of the FFT across...
As shown in the figure, a square wave and sine wave may have identical peak voltage levels but the RMS value or the root mean square value may not be identical. This aspect is what that makes a square wave particularly different from a sine wave even though the peak value may be the ...
which are used to step up or step down the voltage levels. 230V AC is converted into 12V AC using a step-down transformer. 12V output of stepdown transformer is an RMS value and its peak value is given by the product of square root of two with RMS value, which is approximately 17V...
The sound pressure is the alternating sound pressure as RMS value. The sound pressure amplitude is the peak value of the sound pressure. The sound volume (loudness) is determined mostly by the sound pressure p and expressed as sound pressure level Lp in dB. Comparison of sound pressure level...
dBm is a power ratio relative to 1mW, dBu and dBV are voltage ratios, relative to 0.775V and 1V, respectively. To use this calculator enter your application data in the section provided, then enter the quantity you wish to convert in the appropriate form element. Tabbing to another field,...
