Ohm My Goodness!
This unit measures electrical current.
What is the ampere (amp)?
This type of conductor is commonly used to carry electricity through building wiring.
What is copper?
This handheld instrument measures voltage, current, and resistance.
What is a multimeter?
This device automatically opens a circuit when excessive current flows.
What is a circuit breaker?
This device is used to turn a light on and off.
What is a switch?
This law states that voltage equals current multiplied by resistance.
What is Ohm’s Law?
This wire color is commonly used for the equipment grounding conductor in U.S. wiring.
What is green?
An electrician uses this tool to tighten or loosen screws.
What is a screwdriver?
This protective device melts when too much current flows through it.
What is a fuse?
This common lighting source produces light by passing electricity through a filament.
What is an incandescent bulb?
A circuit has 120 volts and 10 amps of current. This is its resistance.
What is 12 ohms?
This device connects electrical wires together and provides a safe enclosure.
What is a junction box?
This tool is designed to strip insulation from electrical wires.
What are wire strippers?
This device is designed to protect people from electric shock caused by ground faults.
What is a GFCI?
LED stands for this
What is Light-Emitting Diode?
This unit is used to measure electrical resistance.
What is the ohm?
his term describes connecting electrical components in a continuous path where the same current flows through each component.
What is a series circuit?
This tool is commonly used to pull wires through conduit
What is fish tape?
GFCI stands for this.
What is Ground-Fault Circuit Interrupter?
This type of switch allows a light to be controlled from two different locations.
What is a three-way switch?
If resistance increases while voltage stays constant, current will do this.
What is decrease?
In this type of circuit, components are connected on separate paths, allowing current to flow through multiple branches.
What is a parallel circuit?
This tool measures electrical current without requiring the conductor to be disconnected.
What is a clamp meter?
This device protects a circuit from excessive current by interrupting the circuit when its rated current is exceeded.
What is an overcurrent protection device (OCPD)?
This lighting technology uses semiconductors to produce light and is known for high energy efficiency and long life
What is LED lighting?
