p_y_r_o Posted April 5, 2006 Posted April 5, 2006 HiI'm making a marx generator and i was wondering weather two 500 killer ohm 0.5 watt resistors could be used in place of a 1 mega ohm 1 watt resistor?
Zeppelin Posted April 6, 2006 Posted April 6, 2006 Do you mean kilo-ohm? If you do, just hook them up in series.
snow Posted April 14, 2006 Posted April 14, 2006 nop you cant if you put them in paralel you can get 1W while it will be 1\R1+1\R2 so you dont get the right resistensebut if you put them in series like chaplin sayed you can get only 0.5Wand 1 M ohm...
Boomer Posted April 18, 2006 Posted April 18, 2006 Would you mind to refrain from teaching bullshit? Each one is built to dissipate half a watt, so how much can two of them dissipate? ONE WATT! For a Marx it hardly matters what value you take, as long as it is not so low it discharges the caps before all spark gaps trigger, or so high the upper caps don't have time to charge. Since you won't be able to reproducibly build 500V or 1000V spark gaps, due to the high voltage per stage series connection is preferred, otherwise they can short. Half watt resistors are rarely made for over 300 volts (but break down at several times that). BTW he was right, once you get to 20 kilovolts per stage (like my 200kV unit that only puts out crappy 120kV due to bad construction), you really need KILLER resistors!

al93535 Posted May 19, 2006 Posted May 19, 2006 Snow: You need to use better grammer. ALL of your posts look like crap. Please capitalize, use punctuation and form sentences. And refrain means to stop.
ltf Posted May 19, 2006 Posted May 19, 2006 חח סנו מה קורה אחי? זה ליברמן..My English & your's are the same, but I'm using a dictionary http://milon.morfix.co.il/Default.aspx.I know my message deosn't related but I know snow from the israely pyrotechnic forum and I don't want that some of us will make the Israely pyrotechnic community to look bad

FrKoNaLeaSh1010 Posted May 21, 2006 Posted May 21, 2006 Does this look like a fucking hebrew forum. No disrespect but speak fucking english on an english forum. It was created by english speaking people.....english is the picked language so that is what you use. If you wanna speak hebrew go back to ur fucking israeli pyro forum.
