Professional engineers-HELP!?

Question

This is a science experiment ive been so crazy about lately! i can't get it right!!!!
okay. My point here is to see which energy sources produce the highest voltage.

im using a 3 volt battery, a dc generator, a voltaic cell[vinegar], and the human body[static] .

problems are: can you make a simple generator? i just want something using electromagnetism to light up a lightbulb! and how can i measure the voltage produced by the human body[static]?
[also for the body one, is there another way to light up a lightbubl using static?]

please, tell me where to place the voltmeter and with specific directions on how to measure everything/
and also tell me personnally what you think of this project.

Answer 1

A conventional light bulb requires a fairly significant amount of electricity. It would be much easier to light a small bulb like a flash light bulb. It would be easier still to light a LED but LEDs (light emitting diodes) oonly work if the electricity (DC) is flowing in the right direction.

Electricity will only flow if there is a complete circuit but you can measure the voltage whether there is electricity flowing or not. Use your volt meter to measure across load, on the two ends of the wire that will be connected to the light bulb.

A battery and a dc generator will certainly work. A home made battery will work using two different metal electrodes in an acidic or basic solution.

Static electricity will be more difficult to measure because, typically, the static charge builds up and is dissipated in one sudden arc, like when you touch a door knob. To create a current using static electricity, you need a constant source of static electricity. You might be able to create enough constant static electricity with some type of wheel where you have brushes in contact with a moving disk.

Answer 2

There is no such thing as a heating engineer. There are heating technicians, HVAC technicians, but not engineers. These are tradespeople. An Engineer is someone who has graduated from a university with at least a 4 year BS or BE degree in engineering. A Professional Engineer (PE) is an engineer who has passed the Engineer in Training exam, has 8 years of relevant work experience, and then has passed the Professional Engineer exam, a very rigorous exam given by professional engineering societies.
