Description: Students will be tested on their knowledge of electricity and related concepts. The exam will cover circuits, conductors, voltage, current, resistance, schematic drawings, meter readings, electrical sources and safety.

No measurements or calculations on parallel circuits.
There could be measurements or calculations on series circuits. If there is, it will just be simple addition or subtraction.
Know their effect on a circuit. They may have to identify it's use in a circuit, ie Will a bulb light or not. They may be asked to use on 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.
The answer would be NO, since the switch is open and no current can flow to the bulb.
There will be no measurement or calculation of resistance of parallel circuits.
Yes- there could be questions on SPDT, DPST, DPDT in the drawing section. You can see examples in the extravaganza handout.
There could be SPST, SPDT, .DPST switches in the construction area.
Possibly - but it would only require addition and subtraction.No complex calculations (as in resistance of a parallel circuit)
Schematic symbols only. Pictorial drawings will not be given credit.
No- Not this year.
Yes. This year there will be some questions on the resistor color code
They will be told specifically what piece of equipment to use at each station. The "Multimeter" Station and the "Build a Circuit Tester" Station have been separate stations for many years now to avoid confusion, so they would not have the option to construct a meter or use a multimeter at the same station. The Circuit Tester is never pre-constructed, but would have to be built by the students at that station.
The Mystery Cards card could be either at the "Multimeter" Station (the students would be instructed to use the Multimeter to answer the questions at that station)and/orthe "Build a Circuit Tester" Station (the students would be instructed to Build a Circuit Tester to answer any questions at that station).
Below is the Heading on Station #4 and Station #5 from the 2015 County Event:
Station #4 – Meters: Multiple Choice
Use the Meter & the Materials in the box to answer the questions
Station #5 – Circuit Tester
If necessary, build a Circuit Tester to answer the questions at this station
Example submitted with FAQ:
if the resistance of a resistor is 15, with a tolerance of 10%, will they need to identify the resistance as 13.5 - 16.5 Ohms, or will 15 +/- 10% be sufficient?
Supervisor's response:
Your question would be broken down into 2 parts on the exam
What is the resistance of the resistor shown? Answer 15 W
What is the tolerance of the resistor shown? Answer +/- 10%

4 Band.
I'm looking to see if 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
What is the resistance of the resistor shown below?
Answer: 230 Ω
What is the tolerance of the resistor shown above?
Answer: +/- 2%
I generally like to ease into a new topic. A color code chart will be 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.
Example question is in the Coaches Workshop handout.

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)
We WILL NOT be using a motor at the tournaments.
