The three methods that voltage forces current to flow are direct current, alternating current, and pulsating current.
Ohm's law is represented using a triangular diagram to determine the proper formulas to calculate voltage, current (amps) and resistance.
Using the triangle that represents Ohm's law, the formula for calculating current is
E = I x R
R = E/I
I = E/R
What is the wattage of a 120 volt household light bulb that has a resistance of 192 ohms and uses .625 amps? (P = I
None of the above
A magnetic field consists of lines of force, which are more commonly referred to as flux lines.
A(n)________is the basic unit of power, the amount of work accomplished when one volt causes one ampere to pass through a circuit.
The instantaneous value of a sine wave is the value at any particular time from zero to the peak value.
Single-phase is used where large blocks of power are required in commercial and industrial facilities.
The peak value of a sine wave occurs at the positive maximum and again at the negative maximum.
In the United States, Alternating Current (AC) is generated at ____________ hertz.
None of the above
Electrons can be freed by applying an external force, such as movement through a magnetic field, heat, friction, or a chemical reaction.
Electromagnetism is an interaction between electric current and a magnetic field.
Despite the fact that it has been positively determined that electron flow is the correct theory, conventional flow theory still dominates the industry.
Electromagnetism is an interaction between a magnetic field and a voltage source.
If the diameter of a conductor is doubled, the resistance is doubled.
Voltage is the rate at which energy is drawn from a source that produces a flow of electricity in a circuit.
Insulators are materials that don't readily give up electrons, thereby restricting the flow of current.
The current flow in a parallel circuit divides itself between the branches back to the source.
The voltage value as measured across each resistor or load, in a series circuit, is called
In a series circuit, when more than one resistance is in the circuit, the resistances are multiplied together to get the total resistance. (R
