DC/AC Theory
You have a 10 ohm, 20 ohm and 30 ohm resistor connected in series to a 24 volt source. This is the number of paths for current flow found in this series circuit.
one
This is the total opposition the current flow in a DC circuit.
resistance
Farmers often use this to keep animals out or in.
Electric fence
This article of the National Electric Code is the main article to look at when seeking information on branch circuits.
Article 210
This is an electrical device that uses electromagnetism to change voltage from one level to another or to isolate one voltage from another.
transformer
This is the total opposition to current flow in an AC circuit that contains resistance, capacitance and inductance.
impedance
A branch circuit that consists of two or more ungrounded conductors that have a voltage between them, and a grounded conductor that has equal voltage between it and each ungrounded conductor of the circuit. And that is connected to the neutral or grounded conductor of the system.
Multiwire branch circuit
Prisoners in some states may find their end of the road here.

This table should be used to determine the full load current values for all calculations with the exception of overloads for a three-phase motor.
Table 430.250
This type of magnetism is used to convert electrical energy to a rotating mechanical force on a motor shaft.
Electromagnetism
A heating element in a heater has a resistance of 25 ohms and draws a current of 10 amperes. This is the amount of power in kilowatts that is dissipated in the heater.
2.5 kW
The purpose of the code is the practical safeguarding of this from the hazards arising from the use of electricity.

For a charged up time you may find it on this road in the city.
Electric avenue
This table should be used to determine the minimum burial depth for all wiring methods 0 to 1000 V.
Table 300.5
What do they call the opposition to current flow created by any capacitor in a circuit?
Capacitive Reactance (Xc)
What do they call the opposition to current flow created by any inductor in a circuit?
Inductive Reactance (XL)
The name of the formula most often used for all calculations in a DC series or parallel circuit.
Ohms Law
This is the term applied to power being generated with flowing water.
Hydroelectric
Based on three conditions and on the nominal voltage to ground, which table should be use to determine the minimum clearance distance for working space?
•Table 110.26(A)(1) ….. Table 110.26 is acceptable.
A common but perhaps overlooked conductor is the surface or subsurface of this.
Earth
This is the amount of current flowing in a SERIES CIRCUIT with an inductor having a reactance of 40 ohms, a capacitor having a reactance of 24 ohms and a resistor of 12 ohms...voltage 120 volts. You do get an extra minute on this one. :-)
6 amps
This is the "Dan" reason why transformers hum.
They don't know the words.
This is commonly seen during the celebration at many weddings.

•What is the main table used for determining how much current a wire can handle with the following conditions:
60° C through 90° C
Not More Than Three Current-Carrying Conductors in a Raceway, Cable, or directly buried.
