Definition
This is the difference in electrical energy between 2 points in a circuit.
What is voltage?
This is the unit used to measure voltage.
What is a volt?
These are the 2 main parts of an electrochemical cell.
What are electrolytes and electrodes?
These are the 3 basic parts in a circuit.
What is an energy source, a load, and wire/pathway?
This is the degree to which a substance opposes the flow of electric current through it.
What is resistance?
This is the symbol for resistance.
What is R?
Like the copper-plated penny and the zinc-plated nail in the lemon battery, these are metal strips that react with the electrolyte in an electrochemical cell.
What are electrodes?
This is an electric circuit where the devices are arranged in parallel paths.
What is a parallel circuit?
This the amount of electric charge that passes by a point in an electric circuit at a given time interval.
What is electric current?
This is the symbol for current.
What is I?
This is a liquid or paste that conducts electric charge because it has chemicals that form ions.
What is an electrolyte?
This is an electric circuit where the components are arranged one after another.
What is a series circuit?
What is an electrochemical cell?
This is the unit used to measure current.
What is an ampere/amp (A)?
A type of cell that uses a paste as its electrolyte. It is often found in flashlights, phones and other hand-held devices.
What is a dry or a primary cell?
What is an open circuit?
This is any material that can slow down current flow.
What is a resistor?
This is the unit used to measure resistance.
What is an ohm (Ω)?
What is a wet cell?
What is a schematic diagram?
