Author Topic: Ohms Law Explanation Peter David Bruce Expert Film Handler Posts: 187 From: East Anglia -England Registered: Aug 2007 posted 11-30-2007 03:10 AM                    well i understand the basics.... maths was never a strong point for me... so hopefully with further training I can get up to scratch on that. My key strengths for this interview will be my actually approach to the job. Mathematics is always important, which is why i had to ask about ohms. My previous proj manager has helped me out with this... and really I shouldnt have a problem. I just really want to make this job work for me. in a good way! not commandeering the whole place but just to have the power to guide the company into the future. Ohms... ok so I=E/R ... if E is reduced and R is increased, I will decrease. And vice-versa. Makes rough sense. to be truthful, I have already shown my knowledge of the projectors and how they all work, solving issues etc. Plus my ability with the paperwork and Rota etc.... Should bode well. I will post in my interview topic later how I feel it went. Dont know how long it will take to hear the result. Only two people have applied for the role, and I am friends with the other guy, so either way it will work out for the better.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 11-30-2007 03:25 AM                     ..to add to the Power thing: I call it the "pie" formula - being P=IxE. Simply put, Power (wattage) = current (I) times (E) voltage - the simple way we chek how much wattage is the bulb using by taking the amp reading and times it by the DC voltage coming out of the power supply. When you open a new bulb box (esp with the Christies..) there is a card there that the technician at Christie has written down the initial voltage, current and wattage run on that new bulb ..which is the same as the formula above.  |  IP: Logged Peter David Bruce Expert Film Handler Posts: 187 From: East Anglia -England Registered: Aug 2007 posted 11-30-2007 09:23 AM                    excellent,. thankyou all so much. Just had my interview for manager. couldnt have done it any better and I made a good impression. Now its a waiting game. I really had to show them what i knew about the ohms law and apparently i got it just right! whoo!  |  IP: Logged David Graham Rose Expert Film Handler Posts: 187 From: Cambridge, UK Registered: Sep 2002 posted 12-01-2007 03:08 AM                     y=ASin(wt+/-phi)  |  IP: Logged Peter David Bruce Expert Film Handler Posts: 187 From: East Anglia -England Registered: Aug 2007 posted 12-01-2007 12:15 PM                    ok now im confused.  |  IP: Logged Chris Slycord Film God Posts: 2986 From: 퍼항시, 경상푹도, South Korea Registered: Mar 2007 posted 12-01-2007 12:35 PM                     That's the equation for AC voltage time dependence V(t) = Vm * sin (wt + phi) Where Vm is max/peak voltage w is angular frequency; same as 2*Pi*f where f is the regular frequency And phi is the phase difference between current and voltage.  |  IP: Logged Jon Miller Jedi Master Film Handler Posts: 973 From: San Diego, CA, USA Registered: Sep 1999 posted 12-01-2007 09:18 PM                     quote: Monte L Fullmer ..to add to the Power thing: I call it the "pie" formula - being P=IxE. To make things simpler, think "West Virginia," for watts equaling volts times amperes, or W=VA.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 12-02-2007 02:11 AM                     Ya, that works too. Just like the little 'story' to represent the electronic color code: 00-Black 01-Brown 02-Red 03-Orange 04-Yellow 05-Green 06-Blue 07-Violet 08-Grey 09-White "Brahma Bulls Raised On Young Grass Brings Very Good Wages" ..and I'm sure there is plenty of 'story' variations to represent this code. -Monte  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 12-02-2007 09:46 AM                        That's not the one I use.....Violet gives willingly!

Take three colors a day, and everytime you see one of those colors that day, think of the number for that color. In less than a week, you'll learn the color code by sight.  |  IP: Logged Peter David Bruce Expert Film Handler Posts: 187 From: East Anglia -England Registered: Aug 2007 posted 12-03-2007 09:20 AM                    thanks, tim, thats a good way to learn it. Also, it never hurts to have this all written down infront of you anyway.  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 12-03-2007 11:20 AM                     I always had trouble with Violet "giving", apparently silver and gold were required.  |  IP: Logged Rick Raskin Phenomenal Film Handler Posts: 1100 From: Manassas Virginia Registered: Jan 2003 posted 12-03-2007 02:22 PM                     I remember them talking about Young Girls Behind Victory Garden Walls.  |  IP: Logged
