Measuring
What is an Ammeter?
It is the movement of electrons flowing through a conductor
What is Electricity?
It allows the free flow of electric current through itself.
What is a conductor?
The ultimate source of virtually all energy.
What is the Sun?
They are the unit of resistance
What are Ohms?
It is analogous to water pressure in a mechanical system.
What is voltage?
They inhibit the flow of electric current.
What is an Insulator?
It cannot be replaced once it's used.
What is Nonrenewable Energy?
They are the unit of measurement for potential difference.
What are Volts?
It is the electric charge or number of electrons flowing through a unit area in a given time.
What is Current?
Under some conditions they act like a conductor but may act like an insulator also
What is a Semiconductor?
It uses nuclear fission to release useful energy and it is radioactive.
What is Uranium?
It is the unit for electric current.
What is an Ampere?
It is a device which opposes the flow of electric current
What is a Resistor?
Which one of these does not belong?
CONDUCTORS: copper, plastic, iron, graphite, aluminum
What is plastic?
Wood is the most common plant material but animal waste is also a source for this type of fuel.
What is Biomass?
It can measure AC or DC voltage, continuity, current and resistance.
What is a multimeter?
A statement that describes a relationship between voltage, current and resistance.
What is Ohm's Law.
Which one of these does not belong?
INSULATORS: wood, porcelain, glass, graphite, cotton
What is graphite?
The country where almost 90% of the people use geothermal energy - though it is not the largest producer of this type of energy.
What is Iceland?
