Words that start with "I"
A component that resists changes in current.
What is an inductor?
A four-letter word for an inductor.
What is coil?
The abbreviation for the number of cycles that occur every second.
What is Hz?
The standard frequency of the power grid in the US.
What is 60 Hz?
A component that dissipates energy through heat.
What is a resistor?
What is inductance?
A material that will increase inductance when used as a core in an inductor.
What is iron (or steel)?
The one-letter symbol that means a measurement in Amps.
What is I?
It's an amount of time for one full AC cycle.
What is period?
The resistance of an ideal, "pure" inductor (even though there's no such thing).
What is 0 ohms?
Something that only happens when a magnetic field changes.
What is Induction?
"An induced current always flows in a direction that opposes the change that caused it."
What is Lenz's Law?
The one-letter symbol that represents the amount of Henrys in a coil.
What is L?
The voltage peak times 0.707.
What is RMS?
It's used to calculate impedance, when resistance and reactance are known.
What is the Pythagorean Theorem?
It's measured in Ohms.
What is Inductive Reactance? (or Impedance)
The shape of the magnetic field around a single current-carrying wire.
What is a circle?
The one-letter symbol for the combination of resistance and inductive reactance.
What is Z?
The businessman on Nikola Tesla's side during the War of the Currents.
Who is George Westinghouse?
What would happen if you leave a battery connected in a complete circuit to nothing but a small inductor.
What is short circuit?
When voltage and current both peak at the same time.
What is "In-phase"?
A verb that describes a magnetic field during inductive kickback, synonymous with "fall down."
What is collapse?
A letter that sometimes means Voltage, but isn't the letter V.
What is E?
The other variable that affects the amount of inductive reactance in an inductor, besides inductance.
What is frequency?
A basic formula you can use to find inductive reactance in a purely inductive circuit (without knowing L).
What is Ohm's Law?
