What, in electricty, do the unit "volts" measure?
Volts measure the pressure in which electricity will flow.
100
What is a watt used to measure?
It measures the amount of work done by a certain amount of current at a certain pressure
100
What does an ampere measure?
It measures the amount of electric current.
100
What is the definition of charge?
The charge is used to measure how much electricity is actually there.
100
What is resistance?
How tightly material is holding onto electrons.
200
What is the scientific symbol for voltage? Hint: This dates back to early days of electricity when it was called "Electromotive Force."
The scientific symbol for voltage is E.
200
1000 Watts= 1
What is the kilowatt
200
Who is the term ampere names after? Hint: a french mathematician and physicist.
The term ampere is named after André-Marie Ampère, who is considered the father of electrodynamics.
200
What is the definition of a Coulomb?
The Coulomb is the unit normally used to measure large charges.
200
What are 3 things that the multimeter can measure?
A multimeter is a device that can measure 1. voltage 2. amps 3. resistance
300
What has more electricity: a 12 volt car battery or a 1.5 volt flashlight.
A 12 volt car battery will have more electricity than a 1.5 volt flashlight. The higher the voltage, the more electricity that will flow.
300
The word Wattage was given to honour this man. Hint: He was the inventor of the steam engine.
Who is James Watt?
300
What does Ampère's force law state.
Ampère's force law states that there is an attractive or repulsive force between two parallel wires carrying an electric current.
300
What is the definition of a current?
The electrical current is a measure of how much electricity passes a given point in a certain amount of time.
300
What unit of electricity is current measured in?
Current is measured in Wattage (Watts.)
400
Who is the unit "volts" named after?
The unit "volts" is named after Alessandro Volta, an Italian physicist known for the making of the electric battery.
400
750 watts is equivalent to what unit of electricity?
What is 1 horsepower.
400
How many amps does a typical household circuit carry?
A typical household circuit carries between 15 to 50 amps.
400
What is an Ohm?
The Ohm is the unit of electrical resistance.
400
Who is the term Coulomb named after?
Charles Augustin, a French physicist who pioneered research into magnetism and electricity

Why would knowing the wattage of your microwave oven help you when making food?
Knowing the wattage will help you know how to properly cook the food in order to make sure it reaches the required temperature. This is a matter of food safety.
500
What is one device that can be used to measure amps?
A device that can be used to measure amps is a digital multimeter.
500
What is frequency?
Frequency is the number of times that the current goes through a complete cycle per second.
