How can i get pulsating 3000v dc voltage to steady ac voltage around 220v

Not easily. How much power/current capability does the 3 kV have? What is the pulsation rate? What frequency do you want at 220 volts? In theory, you can AC couple the 3 kV via a capacitor, into a tr

Can i build fighter jets, helicopters, for the USA or engines for these things with a degree in mechanical engineering. thanks-You can work for a company that does. They are Lockheed Martin, Northrop

Do you know how to find the equivalent resistance

Im using a TI-84 plus calculator and for some reason my answer comes out different than what it should. (Find the equivalent resistance in the circuit shown above, which is R1= 11 ohms, R2= 7.00 ohms

What is a vector and equilibrium in layman's terms

A vector is an element with magnitude + adirection.Think of it like a line.The length would be the magnitude and the direction would be it orientation, or which way its pointing.Like a compass needle.

Is it possible to use solar power to operate my uncle's pacemaker

Its possible but silly. He would have to have some solar cells on his head. He has to always be in the sun or under a bright light or his heart stops. At night he has to sleep with a bright light shi

Which is better ac or dc generator

so yeah.-If you live in America, we use AC outlets, so that is the type of generator that you will want, unless your generator comes with an adapter that will convert DC power to AC. If you live in

In steel-framed buildings, what do you call this kind of support column

Electrical Engineering, Diodes help

For diodes, by increasing forward voltage drop across it, what will happen, to allow more carriers to flow cross the PN interface?-The current will increase if you increase the voltage. And it increas

How can i determine/identify the watts of a resistor

it is easy to read the resistance of a resistor, but to identify its watts is difficult, so i need help. please explain it briefly. what resistor i am pertaining to are the color-coded resistors, and

How can one make a firework ignitor from a common 9v battery

I have tried and failed about 50 times... any help? I have the switch and button part just not the part that makes the spark to light the fuse.-You could use a piece of nichrome wire. It wont spark b
