You can, but it will not sound loudly. A microphone always needs a pre amplifier.

The SI unit of electric current is the ampere. While it is an SI base unit, it can also be considered to be a combined unit, coulombs per second.

A step-down transformer U really don't need a step up or stepdown transformer You need a source capable to run your LED it can be a swithcing power supply for istance a battery

You can call Coserv (the authorized Seiko Service Center) at 201-529-3316. They are located in Mahwah, NJ.

i need to know as well.

Hfe is an empirical value it means nothing unless a load is considered. the meter probably does not provide the proper loading so why measure it?

you have to already have regigigas but i only know the areas mt. coronet,iron island,and i think route 228.

Wind energy can harm migrating birds.

They are also considered an 'eye sore' on the landscape.

When you consider how much energy went into the manufacture of the turbines, against how much energy they produce, it appears they have a larger 'carbon footprint' than is first thought.

To get security armor in Halo 3... all you have to do is get all of the original 49 achievements (you don't need the new mythic or legendary achievements).

I am not sure, but I am also trying to find out if my Mr Peanut ride on toy that has to be at least 50 years old from the Worcester Toy Co is worth anything.

i want to irf 3205 capacity for drawn curent.

Many job site radios like the Makita have an auxillary plug or two to plug in an Ipod/mp3 player or a portable CD player.

Total slots per phase =12/3=4 slots to be occupied.

Slots per pole per phase = 12/(3*4)=1

hence for A phase, the slots to be occupied are 1,4,7,10;for B phase, the slots to be occupied are 5,8,11,2;for C phase, the slots to be occupied are 9,12,3,6 and winding to we wave type.

Today about $2.00 if not less.

good luck finding one

No, it will run out just as much as if you put it in a series circuit. Parallel circuits involve the same voltage or amperage to go to each component.

Lets put a value to the transformer, say 500 VA. Step down with a 5:1 ratio. Say 250 volts on primary. 250/5 = 50 volts secondary. 500 VA transformer/50 volts secondary = 10 Amps. Therefore the secondary would have to have the larger wire to accommodate the larger current.

Otis F. Boykin invented the wire precision resistor and the electrical resistor. In June 1959, he got the first patent for the wire precision resistor and in June 1965, he got his patent for the electrical resistor.

The most common voltage supply to homes is single phase 120V / 240V. In the states for industries, 3 phase 480 Wye 277. In Canadian industries, 3 phase 600 Wye 347 volts.

Peak DetectorA peak detector determines the peak voltage on an ac wave and converts it into a dc voltage. A diode puts the peak voltage on a capacitor. The second op amp is a buffer. This means it holds the same voltage input and output, but it allows current to be used at the output without altering the voltage. An op amp buffer is created by connecting the output to the inverting input.The purpose of the buffer in this instance is to tell the first op amp what the voltage is on the capacitor. In simple designs, this is done by simply connecting the inverting input of the first op amp directly to the capacitor. But the buffer allows a second diode to be used in the feedback loop without altering the capacitor voltage. The diode then pulls against the output of the buffer instead of the capacitor.The purpose of the feedback diode is to prevent the output from saturating on the down-swing. Saturation means the output goes to the supply rail, while excess current is drawn through the input, which can create undesirable effects. The feedback diode pulls the inverting input down to the same level as the noninverting input, which means the output is never more than 0.6V lower than the noninverting input or the bottom of the voltage swing on the ac input wave. The feedback resistor allows a difference in voltage to be created between the inverting input and the output of the buffer.The design challenge of a peak detector is in the fact that the diode pulls the voltage up but not down. Something needs to bring the dc voltage on the capacitor back down, either when the voltage being measured decreases, or when an over-voltage spike is created for some reason such as noise, contact of leads or turn on of the device.Leakage current through the diode when reverse biased will be enough to control the capacitor voltage when stable measurements are being made. At other times, more current is needed to bring the capacitor voltage down. A resistor can be used for that purpose. But it will then create some ripple on the capacitor, because it will be pulling voltage down while the diode is not pulling it up. The ripple is greatest for lowest frequencies, because then there is more time during each cycle for voltage to decrease. Therefore, low frequencies require some compromise between ripple on the dc and rate of equilibration.Here's how to calculate ripple on the capacitor. Start with this formula: V/S = I/C. It says volts per second equals current over capacitance. Say there is one volt on the cap. Divided by 10M of resistance equals 0.1µA of current. Divided by 0.47µF equals 0.213 volts per second. If the frequency is 10Hz, there is 0.05 seconds for each half of the wave. So 0.213V/S times 0.05S equals 11mV of ripple. If the frequency is increased to 1KHz, a half wave is 0.5mS, and ripple is 0.0005 × 0.213 = 0.11mV. If the cap voltage is increased to 2V, the ripple is 0.21mV, or twice as much, but the same percent.The rate at which the voltage equilibrates is not linear. At 1V on the cap, it is 0.213 volts per second; but at 2V, it is 0.426V/S. So it would take about 3-5 seconds to equilibrate when 1V too high. Pulling it down instantly with a push button switch is so easy that it is better than compromising the design or waiting for equilibration.

Pretty much all 303,591,568 of us. (yes, even the Amish and the homeless use electricity).

the percentage of people that use electricity is 97%! :D that also, means that only 3% don't use electricity. :(

Light and other electromagnetic waves do indeed travel as a wave. For that reason, light, radio waves and all other electromagnetic waves can be characterized by a wavelength. Different colors of light have different wavelengths in the range of around 400 nanometers to 800 nanometers.

However, they can also be considered to be particles instead of waves. In some branches of physics, the concept of light as a particle can be very useful. For most of us, treating light as a wave is quite sufficient.
