The Basics of Spark
When force is applied to these specific electrons, they break free and create an electric charge.
What are valence electrons?
This is a complete and closed path that allows electricity to flow.
What is a circuit?
These specific wires carry voltage or "pressurized" current.
What are hot wires?
On a light switch, the grounding or copper wires should be secured to this color screw.
What is green?
Use this tool to remove a portion of a wire’s insulation.
What is a wire stripper?
This term describes a material’s tendency to resist the flow of current.
What is resistance?
Because this type of circuit is incomplete, electricity cannot flow and it is not functional.
What is an open circuit?
This term refers to the current-carrying capacity of a wire.
What is ampacity?
In a standard insulated sleeve, this color usually represents the "neutral" wire.
What is white?
Use this tool to twist wires together clockwise before capping them.
What are linesman’s pliers?
This type of current flows in only one direction and is typically used in battery-powered devices
What is Direct Current (DC)?
This dangerous event occurs when electricity flows away from its intended path, potentially causing sparks or fires.
What is a short ciruuit?
(DAILY DOUBLE)!!!
As this number decreases, the thickness of the copper and its ability to carry current increases.
Black or HOT wires are attached to these colored screws on the right side of a switch or outlet.
What is bronze?
This safety device is used to cover the exposed ends of twisted wires.
What is a wire nut?
He published a law in 1827 stating that current is proportional to voltage and inversely proportional to resistance.
Who is Georg Ohm?
In this type of circuit, the same current flows through all components simultaneously along a single path
What is a series circuit?
This wire carries zero voltage or "non-pressurized" current.
What is a neutral wire?
When wiring a wall outlet, you attach the neutral wires to these colored screws.
What is silver, or stainless steel?
This tool should be used to confirm the power is actually off before you start working.
What is a voltage meter?
This is the name for an electrical potential or potential difference, measured in volts.
What is voltage?
This circuit provides individual paths to each component, ensuring they all get a charge even if one part fails.
What is a parallel circuit?
Most residential wiring systems include this many total wires coming in from the road.
What is 3?
This color wire is the HOT wire in typical residential wiring.
What is black?
This is the name of the following formula:
V = IR
What is Ohm's Law?
