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...
What average power must the motor develop to produce this acceleration? Give your answer in horse power (1 hp = 746 W) 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 ...
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...
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...
Power consumption in circuits is defined as how much energy is delivered per unit of time. The units for power is watts. In DC circuits, power...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough ...
