Static Vibes Only
This is the overall charge an atom gets if it has more protons than electrons.
What is a positive charge?
A material, like copper or silver, that allows electricity to flow through it freely.
What is a conductor?
This is the unit of measurement used for electrical resistance.
What is the Ohm?
This is the equation that describes the relationship between potential difference, current, and resistance.
What is Ohm's Law (V = I x R)?
This is the rate at which electrical energy is produced or used, and it is measured in Watts.
What is electrical power?
This fundamental law states that opposites attract, and likes repel.
What is the Law of Electric Charges?
A circuit where the flow of electrons follows only one continuous path.
What is a series circuit?
You use this specific device to measure potential difference, and you must connect it this way in the circuit.
What is a voltmeter, connected in parallel?
If a circuit has a 12 V battery and a 3 ohm resistor, this is the current flowing through it.
What is 4 Amps?
This label is found on all household appliances to help consumers estimate how much electrical energy the appliance will use in one year.
What is the EnerGuide label?
This is the list you check to see which material is going to steal electrons when two objects are rubbed together.
What is the Electrostatic Series?
If one bulb burns out in this type of circuit, the rest of the components will continue to work.
What is a parallel circuit?
In the water pipe analogy, this electrical property is represented by the pressure pushing the water forward.
What is voltage (or potential difference)?
Three identical bulbs each use 4 V. If they are connected in series, the battery must be providing this much total voltage.
What is 12 V?
This is the formula used to calculate the percent efficiency of an electrical device.
What is (Useful Energy Output / Total Energy Input) x 100?
This is the process of removing excess charge from an object by connecting it to a large neutral material, like the Earth.
What is grounding?
A circuit component, like a motor or a light bulb, that transforms electron energy into other useful forms of energy.
What is a load?
A wire's resistance will increase if you make these two physical changes to its size.
What is making it thinner (decreasing diameter) and longer (increasing length)?
Three identical bulbs are connected in parallel to a 9 V battery. The voltage across the third bulb is this.
What is 9 V?
A light bulb uses 100 W of electrical energy and produces 35 W of light energy. This is its percent efficiency.
What is 35%?
When a charged balloon is brought near a neutral wall, the electrons in the wall shift their position without actually transferring. This phenomenon is called this.
What is induced charge separation?
The outlets in your home are wired in this way, which is why you don't have to turn on your toaster just to watch TV.
What is parallel?
This measurement remains exactly the same at any point in a series circuit, but divides among the branches in a parallel circuit.
What is electric current?
A parallel circuit has two identical branches. Branch A uses 3.0 A of current. This is the total current leaving the source.
What is 6.0 A?
In Ontario's Time-of-Use pricing system, this is the most expensive time bracket to use electricity.
What is On-Peak?
