Shock Value B

[brobo]

Its all about circuts- electricity, building circuts, resistence, motors, electric motors, ect. You might be asked to build a circut, but most of the time its just a test like most events.
Ask your coach for the official rules. It tells you everything you might need to know/do on them.

I need one more event and was looking at a couple of the open spots for my team and came upon shock value could you tell me what it is about and what you need to study/know?

Read the Wiki.

If a circuit contains two 9v batteries, wired in parallel, would the voltage in the circuit be 9v? Are there formulas for determining those things that we ought to know?

[andrewwski]

Yes. Voltage in parallel stays the same, voltage in series gets added.

[blue cobra]

I don't understand power. The wiki says it's current times voltage, but anything else I am lost on. What exactly is power, how is it used in circuits, and what can we find with it?

[robotman]

Power is the rate at which work is done.(edited so that it was right )
Power is converted into different forms for different things. light energy for light bulbs, heat energy for a heater or sound energy for a speaker.
There are a few things that i think they could ask about power (this is from a worksheet)
An electric space heater draws 15.0 A on a 120 V line. How much power does this heater use?

The full worksheet plus some others are now on the wiki

Thanks, I think I'm starting to get it.

When reading a circuit diagram, are we supposed to assume conventional flow or electron flow? But since there are no semiconductors in this event will it even matter?

[Helix_Nebula_Freak]

I actually think you need to ask the event coordiantior for the type of flow to be assumed...

For most times I would assume that it was conventional flow because most circuit diagrams are asking you what is being powered or what is the resistance.

just to be safe i suggest asking the event coordinator

Power is not the amount of work a circuit can do. That would naturally be work.

Power is the rate at which work is done.

Power is measured in watts. Work is usually measured in joules, but also in watt-hours or kilowatt-hours. 1 kwh equals one kilowatt being drawn for one hour - or power * time.

Conventional vs. electron flow shouldn't really matter when looking at circuit diagrams - the positive and negative terminals of a component (or schematic symbol) don't change regardless of how we think of the electrons as flowing.

But assume conventional flow unless otherwise stated - it's pretty standard. The electron flow model is not used as commonly, although as you know it's actually correct.
