ELECTRICITY VOCAB
This term describes a form of energy that produces light, heat, and chemical changes.
What is electricity?
This type of current flows in one direction only and is used in galvanic devices.
What is direct current (DC)?
This term refers to the positive and negative ends of a circuit.
What is polarity?
This safety device cannot be reused once it melts.
What is a fuse?
Walking across carpet and touching metal causes this type of electricity.
What is static electricity?
These materials best transport electricity, such as copper and silver.
What are conductors?
This is the most common current used in homes and spas.
What is alternating current (AC)?
This waveform has a smooth, continuous rise and fall.
What is a sinusoidal waveform?
This reusable safety device shuts off power when current is too high.
What is a circuit breaker?
Pulling a cord instead of the plug violates this safety guideline.
What is improper cord handling?
This unit measures electrical resistance.
What is an ohm?

What is Pull, Aim, Squeeze, Spray?
This unit measures electric pressure that pushes electrons through a conductor.
What is a volt?
This occurs when too many appliances operate on one circuit at the same time.
What is an overload?
This type of waveform has equal rise and fall times.
What is a triangular waveform?
Dropping an appliance into water causes this dangerous condition.
