If someday complete direct injection spark ignition with gasoline engine with Otto cycle is achieved so that very high pressure ratios are possible, what would be the impact on the automotive industry?
Hey i was wondering if anyone had any sites on how to build a Spark Gap Radio Transmitter, i need to do this for history to show how marconi invented the radio. Thanks- Andrew
Hi, i live in the UK and currently studying physics at A-level. I have chosen to investigate EMP and its effect on electrical systems for a project. How would i build a generator? Am i right in saying all i would need is a fairly large capacitor and a spark gap? What sized voltage are we talking...
Hey, I just signed up and I've already got a question. =)
The answer was in the book but I don't get the answer.
Determie the frequency of a spark timer set at a period of 0.10s.
Ans: 1.0 x 10¹ Hz.
The book only says;
The answer is literally staring me right in the face and the...
in one of my electronics classes, as a group we have to design and build a transmitter and receiver to transmit and receive morse code. we can only use a tesla coil and/or a spark gap for transmission. since we have 3 in our group... i am making the spark gap, someone else - a tesla coil, and...
just a quick question on spark timers, mostly on ticker tape. I need a reminder on how to calculate the acceleration on the tape. i know i need to take a time measurement and the distance between the dots on the tape but from there do i need to calculate intervals or what? I'm using the...
I read this in Feynman's book 'Surely you are joking Mr.Feynman' but I didn't understand it.
'If you close an electrical switch, there will be a spark shortly before the contact is made. If you don't want any spark, just put a capacitor across the switch.'
My question: Why does a capacitor...
