1
What is the wattage of a 120 volt household light bulb that has a resistance of 192 ohms and uses .625 amps? (P = I2 x R).
2
A(n)________is the basic unit of power, the amount of work accomplished when one volt causes one ampere to pass through a circuit.
3
Single-phase is used where large blocks of power are required in commercial and industrial facilities.
4
In the United States, Alternating Current (AC) is generated at ____________ hertz.
5
Electromagnetism is an interaction between electric current and a magnetic field.
6
Electromagnetism is an interaction between a magnetic field and a voltage source.
7
Voltage is the rate at which energy is drawn from a source that produces a flow of electricity in a circuit.
8
The current flow in a parallel circuit divides itself between the branches back to the source.
9
The three methods that voltage forces current to flow are direct current, alternating current, and pulsating current.
10
In a series circuit, when more than one resistance is in the circuit, the resistances are multiplied together to get the total resistance. (RT)
11
Ohm's law is represented using a triangular diagram to determine the proper formulas to calculate voltage, current (amps) and resistance.
12
The voltage value as measured across each resistor or load, in a series circuit, is called
13
Using the triangle that represents Ohm's law, the formula for calculating current is
14
Insulators are materials that don't readily give up electrons, thereby restricting the flow of current.
15
A magnetic field consists of lines of force, which are more commonly referred to as flux lines.
16
If the diameter of a conductor is doubled, the resistance is doubled.
17
The instantaneous value of a sine wave is the value at any particular time from zero to the peak value.
18
Despite the fact that it has been positively determined that electron flow is the correct theory, conventional flow theory still dominates the industry.
19
The peak value of a sine wave occurs at the positive maximum and again at the negative maximum.
20
Electrons can be freed by applying an external force, such as movement through a magnetic field, heat, friction, or a chemical reaction.
