9D1: Energy Transformation Devices
This device converts mechanical energy into electrical energy, commonly used in wind turbines.
What is a generator?
This device is used to open or close a circuit, allowing or stopping the flow of electricity.
What is a switch?
This form of energy is stored in the bonds of chemical compounds and released during reactions.
What is chemical energy?
This type of energy source is derived from the sun and has minimal environmental impact.
What is solar energy?
The class we are currently in.
What is science?
This type of energy is stored in batteries and can be converted to electrical energy when needed.
What is chemical energy?
This component opposes the flow of electric current and is measured in ohms.
What is a resistor?
This type of energy is associated with the motion of objects and can be calculated using mass and velocity.
What is kinetic energy?
The burning of this fossil fuel for electricity generation releases significant greenhouse gases.
What is coal?
The television series on Mr. Dowler's calendar.
What is Star Trek?
This process involves converting thermal energy into electrical energy, often used in power plants.
What is thermoelectric generation?
When a switch is closed in a circuit, this effect occurs, allowing current to flow.
What is conduction?
When measuring the efficiency of a device, this is the ratio of useful output energy to input energy.
What is efficiency?
This renewable energy source harnesses the power of moving air to generate electricity.
What is wind energy?
The age of Mr. Dowler's daughter.
What is four years old?
In a flashlight, chemical energy is converted to electrical energy and then to this type of energy.
What is light energy?
This law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
What is Ohm's Law?
This formula is used to calculate the power consumed by an electrical device, where P is power, I is current, and V is voltage.
What is
P=IV?
The use of this energy source can lead to habitat destruction and water pollution.
What is oil?
The three primary branches of science.
What are biology, chemistry, and physics?
This term describes the transfer of electrical energy through power grids to deliver electricity to homes and businesses.
What is electrical energy transfer?
In a circuit, this is the relationship that describes how voltage, current, and resistance are interconnected.
What is Ohm's Law?
This unit is used to measure energy and is equivalent to one watt of power used for one second.
What is a joule?
This process involves converting organic materials into energy, but can produce methane.
What is biomass energy?
3^4-2*7
What is 67?
