What is the voltage gain of a transistor amplifier that has an output of 5 rms and an input of 250 mV rms?
The voltage gain (Av) of a transistor amplifier can be calculated using the formula ( Av = \frac{V_{out}}{V_{in}} ). In this case, the output voltage is 5 V rms and the input voltage is 250 mV rms (which is 0.25 V). Therefore, the voltage gain is ( Av = \frac{5}{0.25} = 20 ). This means the amplifier has a voltage gain of 20.
What is the peak voltage of a 240 VRMS sine wave?
To calculate the peak voltage of an RMS voltage in a sine wave simply multiply the RMS voltage with the square root of 2 (aprox. 1,414) like this: 240 x 1,414 = 339,4 V RMS x sqr.root of 2 = peak voltage
Are peak-to-peak and rms voltage measurements the same?
No, the peak-to-peak voltage is 2sqrt(2) times as much as the rms for a pure sine-wave.
Use of RMS?
I am not certain what is being asked here. RMS is Root Mean Square which is basically the DC voltage which would produce the same amount of heat in a heating element as the AC voltage in question. Since AC is continuously changing in polarity and voltage, it is handy to use the RMS voltage rather than the peak (169.7V for 120V RMS) or peak-to-peak (339.4V for 120V RMS). The peak or peak-to-peak voltage is handy to know when considering the maximum values such as in rectification.
How rms voltage related to peak voltage?
The average voltage is the rms voltage.Volts peak = volts RMS times 1.414Volts RMS = volts peak times 0.7071Use the link below to an RMS voltage, peak voltage and peak-to-peak voltage calculator.********************************The average voltage is not the r.m.s. voltage.The average voltage of a sine wave is 0.636 x the peak value. Conversely, peak voltage is 1.57 the mean or average.
What is relation between rms voltage and peak to peak?
Vrms=1.414xVpk to pk
Define rms reverse voltage of a diode?
A DIODE will breakdown at a certain reverse voltage if RMS VOLTAGE IS SPECIFIED THEN the actual voltage will be RMS volts times 1.41
What is 10000 rms?
rms stands for root mean squared. rms voltage is a way of measuring a sort of average alterating current voltage as distinguished from peak-to-peak voltage. Likewise for ac rms current.
How do you get kilowatts if given voltage?
If voltage is given as RMS voltage (which it normally is), simply multiply the number of volts by the RMS current (as number of amps), and then divide by one thousand. Power (in kW)=Voltage (RMS volts) * Current (RMS amps) / 1000 (watts/kW)
Is 480 rms or peak voltage?
When people talk about 480V systems, they mean 480 is the RMS voltage.
What is a peak load voltage out of a bridge rectifier for a secondary voltage of 15 Vrms?
A: Peak voltage is RMS multiplied by a factor of 1.41
What is an RMS output?
That is an electric AC or audio output, where the voltage is measured in volts rms. Scroll down to related links and look for "dB conversion (decibel)". Look there in the middle at this headline: "RMS voltage, peak voltage and peak-to-peak voltage".
What is the peak voltage of a sine wave that measure 220V AC rms?
Peak voltage will be 1.414 times the RMS. Peak to Peak voltage, assuming no DC offset, will be 2 x 1.414 x the RMS value.
Effective voltage and maximum instantaneous voltage relation?
For a sinusoidal waveorm, RMS (effective, heating) value = 2/pi x (peak voltage). It's not 2/pi for waveforms with other shapes. 2/pi = roughly 63.7%
What is the conversion for rms voltage to mean voltage?
For an alternating voltage, the simple mean over a cycle would be zero. 'RMS' means 'root mean square', and is defined as the square root of the mean value of the square of the voltage, taken over a cycle. Thus whether the voltage is + or - , as it is in alternate half cycles, the value of its square is always positive, giving a real number for the square root. In fact the RMS value of voltage produces an RMS current which dissipates power at the same rate as a DC current of the same value. To find the RMS value of a sine wave with no DC offset, divide the peak value of the sine wave by square root of 2. **************************************************** Since the r.m.s. value of a sine wave is 1.414Vpk, and the mean voltage of a sine wave is 1.57Vpk, then, starting with the r.m.s. value: Vmean = (Vr.m.s. x 1.414) ÷ 1.57
What is the voltage gain of a transistor amplifier that has an output of 5 rms and an input of 250 mV rms?
The voltage gain (Av) of a transistor amplifier can be calculated using the formula ( Av = \frac{V_{out}}{V_{in}} ). In this case, the output voltage is 5 V rms and the input voltage is 250 mV rms (which is 0.25 V). Therefore, the voltage gain is ( Av = \frac{5}{0.25} = 20 ). This means the amplifier has a voltage gain of 20.
What is the peak voltage of a 240 VRMS sine wave?
To calculate the peak voltage of an RMS voltage in a sine wave simply multiply the RMS voltage with the square root of 2 (aprox. 1,414) like this: 240 x 1,414 = 339,4 V RMS x sqr.root of 2 = peak voltage
