Energy
What is the definition for energy
The ability to do work
This is another name for the battery on a circuit
Source
He was the first one credited with creating a battery (voltaic pile)
When an iron core is inserted into a coil of wire and a current passes through the wire, a temporary magnet called a(n)
electromagnet
This uses a loop of two different metals that conduct electricity at different rates which will allow for a potential difference
Thermocouple
what is this law: energy can neither be created nor destroyed; rather, it transforms from one form to another. All objects have energy but differ in the amount and form of energy they carry.
Law of conservation of energy
This type of energy is created by Squeezing or adding pressure to certain types of crystals generates a small potential difference
Piezoelectric effect
An electrochemical cell has these three parts
Anode, Cathode, Electrolyte
This uses electricity to produce a magnetic field at one end, and an axle (metal rod) rotates at the other end providing mechanical energy
electric motor
Another term for a rechargeable battery
What is a secondary cell
electrical, thermal, mechanical are all examples of this
Kinetic energy
Give an example of where you might find the piezoelectric effect
greeting cards, buzzers, wireless sensors, light up shoes, bbq lighter
In an electrochemical cell, the anode has this charge
Negative
To induce a larger current in an electromagnet, what are two things you could do
•greater amount of loops of wire
•strength of the magnet
•the speed at which the wire or magnet is moved
This is the interaction of electric currents and magnetic fields
Electromagnetism
Heat can be converted directly into electric energy using the
thermoelectric effect
These use energy from the sun to convert light into energy
Photovoltaic cells
What is the difference between a wet cell and a dry cell
Wet cells use a liquid electrolyte, dry cells use a sold/gel electrolyte
What are the two different types of current produced by generators
AC / DC
This is a method that uses the deterioration of the anode to apply the metal ions to another material.
Electroplating
this is several thermocouples working together in series to generate a larger voltage
Thermopile
What does LED stand for
Light emitting diode
How is a galvanic cell different than other types of cells
It has two different electrolytes and uses a salt bridge
This type of current is used to transport electricity from power plant to our homes
AC
Photovoltaic cells (solar cells) use a ____________ (silicon) to capture visible light energy from the sun and allow electrons to break free
Semitconductor
