Flashcards: Circuit Calculations
Ampere
The unit of electric current
Current
A flow of electric charge.
Electrical Energy
The energy of electric charges
Efficiency
The percentage of the input work that is converted to output work
Energy
the ability to do work
Geothermal Energy
Energy from steam or hot water produced from hot or molten underground rocks.
Inexhaustible Energy
An energy source that will never run out.
Nonrenewable Energy
a source of energy that has a finite supply capable of being exhausted
Ohm
Measures electrical resistance
Ohm's Law
The relationship of voltage, current, and resistance
Parallel Circuit
A circuit that contains more than one path for current flow.
Renewable Energy
energy from a source that is not depleted when used, such as wind or solar power.
Resistance
A material's opposition to the flow of electric current.
Work
Force exerted on an object that causes it to move
Turbine
a large wheel that rotates when pushed by water, wind, or steam
Power
The rate at which work is done
Series Circuit
A circuit in which all parts are connected end to end to provide a single path of current.
Volt
The unit of potential difference symbolized as V.
What are the three ways to write Ohm's Law?
V=IxR R=V/I I=V/R
Power Out=
