Energy
What was William Thomson's nickname?
Lord Kelvin
What are batteries referred to in other languages?
"Piles"
What did Alessandro Volta have named after him?
Voltage
What model helps to explain circuits?
The pump model
First law of Thermodyanmics
Energy cannot be created nor destroyed
How many laws are there in Thermodynamics?
three
What happens if the Lithium ions in a secondary cell battery move back and forth too fast?
The battery catches fire
What did James Joule do?
Proposed a connection between work and heat
What particle actually flows in a circuit?
Electrons
What are Equipotential Lines?
Lines that measure voltage (similar to topographic lines)
What are the three forms of energy?
Kinetic energy, Potential energy, Heat energy
How many volts did Volta's battery produce?
30 volts
What did William Thomson do?
Quantified Joule's work into the laws of thermodynamics
What does a resistor do?
Provides an outlet for electric energy to be converted into a useful form of energy
What is DC?
The movement of charge in one direction
What is temperature?
A measure of the average kinetic energy of an object
What term did Benjamin Franklin coin? (and explanation of why)
Battery b/c he used multiple layden jars
What did Volta argue?
The electricity came from the metals, not the animals.
1 mm/s
What is AC?
Alternating current, charges move back and forth quickly
These lines are always perpendicular to field lines.
Equipotential lines
Which rod dissolves in the acid in a primary cell? (Bonus if you can describe the whole process)
Zinc
Acid dissolves zinc -> Acid gains positive charge -> Positive acid polarizes carbon rod -> Carbon is negative inside acid and positive outside acid -> Zinc is positive inside acid and negative outside acid
What did the Galvani sibling discover a link between?
electricity and muscle movement
How many volts is needed to break down the air?
3 Megavolts (3 million volts)
What is Power?
Rate of change of energy over a time
