Charged Up

No.  

The only item students should be bringing into the competition is a pencil.

An LED must be connected with the correct polarity and the correct voltage in order to light up.

The longer lead of the LED is the (+), the shorter lead of the LED is the (-).

The (+) of the battery must connect to the (+) lead of the LED.

An LED requires a power source of two batteries in series (3 volts).

Please refer to the Event Coach Handout and the Kit Study Guide on the website.

There is not a dedicated section on electrical safety. How ever there will be some questions on safety in the True/False and multiple choice questions. 

No parallel circuit calculations or measurements are required.

There could be measurements or calculations on series circuits. If there is, it will just be simple addition or subtraction.

They should know its effect on a circuit, e.g., will a bulb light or not?  They may be asked to use one in a circuit.

There will be no questions with direction of flow.

The arrow on a switch points in the direction of activation... So a Normally Open switch will point from an open position to a closed position.

Yes- there could be questions on SPST, SPDT, DPST or DPDT in the drawing section. You can see examples in the extravaganza handout.

Probably.

There could be SPST, SPDT, DPST or DPDT switches in the construction area.

The model of multimeter we use in our event is a Craftsman model 82140, and looks like this: 

Charged up questions will all be related specifically to electricity.  There will not be any questions on general science terms.

Schematic symbols only.  Pictorial drawings will not be given credit.

No - not this year.

Circuit testers, or the equipment to make one, are provided and students may not bring their own.

Students will be told specifically what piece of equipment to use at each station.  At the "Multimeter" Station, that equipment will be provided for their use.   At the "Build a Circuit Tester" Station, students will have the option to construct a meter.

The Mystery Cards card could be part of either the "Multimeter" Station or the "Build a Circuit Tester" Station.

Example submitted with the FAQ:

If the resistance of a resistor is 15 Ω, with a tolerance of 10%, will they need to identify the resistance as 13.5 - 16.5 Ω, or will 15 +/- 10% be sufficient?

Answer:

This type of question would be broken down into separate parts on the exam.  For example:

     What is the resistance of the resistor shown? Answer: 15Ω

     What is the tolerance of the resistor shown? Answer: +/- 10%

4 Band only.

We want the students understand the color code identification system.

The 5th band doesn't cover any new concepts and only adds some confusion for some students.

Students should know how to use the color code chart, and one will be provided at the station.

To maintain uniformity and fairness, the students are not allowed to bring any reference material or equipment. Everything they need will be provided.

An example question can be found in the Event Coach Workshop handout.

Yes we may be using motors at the tournament.

The motor and propeller are included in the Charged-Up Exploration Kits to add another interesting element to experiment with when learning about polarity and the effect of different voltages.  And it’s fun.

Possibly - but it would only require addition and subtraction.  No complex calculations are required (as in resistance of a parallel circuit).
