The velocity of alternating current traveling through a conductor compared to the speed of light.
What is less than the speed of light?
Another name commonly used for electromotive force (EMF).
What is voltage?
In the standard metric system, this prefix represents the first step above the base unit.
What is deka?
This law states that the electrostatic force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
What is Coulomb’s Law?
In the standard metric system, this is the third prefix above the base unit.
What is kilo?
This law states that in a DC circuit, current is directly proportional to voltage and inversely proportional to resistance.
What is Ohm’s Law?
In engineering notation, this prefix represents the third step below the base unit.
What is nano?
his unit of work equals the amount of force required to raise a one-pound weight one foot.
What is a joule?
This property of a conductor causes a wire to become warm when electric current flows through it.
What is resistance?
In engineering notation, this is the first prefix above the base unit.
What is kilo?
This unit of electrical potential is defined as the amount of potential required for one coulomb to do one joule of work.
What is a volt?
This term describes the flow of electrons through a conductive substance.
What is current?
On the Ohm’s Law chart, this formula is used to calculate current when power and voltage are known.
What is I = P ÷ E?
Engineering notation increases or decreases quantities in steps of this value.
What is 1,000?
This unit is used to measure the amount of electrical power being consumed in a circuit.
What are watts?
Using Ohm’s Law, this is the voltage applied to a circuit with 20 ohms of resistance and 6 amperes of current.
What is 120 volts?
On the Ohm’s Law chart, this formula is used to calculate power when both current and voltage are known.
What is P = E × I?
This SI unit is equivalent to the watt.
What is a joule?
This is the number of base units used in the International System of Units (SI).
What is seven?
This type of circuit occurs when the conductors going to and returning from a power source become connected.
What is a short circuit?
Approximately this many horsepower are produced by an electrical device rated at 3,000 watts.
What is 4 horsepower?
This unit is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.
What is a British thermal unit?
This is the distance, in feet, that a 10-MHz signal travels through a conductor with a velocity factor of 0.66 during one AC cycle.
What is 64.944 feet?
This is the amount of current drawn by a 1,560-watt toaster operating on a 120-volt circuit.
