The measure of current

# data[].attributes.body
How did your experiment contribute to your understanding of resistance?

# data[].attributes.body
Can you see what the equation R = V / I tells you about Resistance?

# data[].attributes.body
How did you use your knowledge of electricity to create your project?

What did you learn through the process?

# data[].attributes.body
What is a parallel circuit?

How does current behave in a parallel circuit?

How does voltage remain constant in a parallel circuit?

# data[].attributes.body
How does the flow of water in a pipe relate to the flow of charge in a circuit?

# data[].attributes.body
What is a series circuit?

How does current behave in a series circuit (constant)?

How is voltage divided in a series circuit?

# data[].attributes.body
How does voltage affect the amount of work electricity can do? *Remember work is a way of saying how much energy can be used to do somerthing.

# data[].attributes.body
How can we use the Hill & Well analogy to understand the behavior of charged objects?

# data[].attributes.body
How does understanding charge help explain static electricity?

# data[].attributes.body
What is resistance?

resistance is something that slows down the current in the wire, such as : obstacles (lightbulb), length of wire, cross sectional area, leaks.

How does it affect current flow?

it slows it down.

# data[].attributes.body
How does the behaviour of current and voltage differ between series and parallel circuits?

# data[].attributes.body
What is current?

How does it relate to moving charge?

What does the equation Q = I  t tell you?

# data[].attributes.body
How can we predict the behavior of current and voltage in series circuits using equations and the analogy?

# data[].attributes.body
What is voltage?

How does it relate to the potential difference between two points in a field?

# data[].attributes.body
What is an electric field?

An electric field is the voltage around a positive or negative charge.

How does it relate to charge?

The charge is shown in the electric field.

What is the "hill and water reservoir" analogy?

it shows electricity like water flowing down a hill. the electricity starts at the water reservoir and flows through a pipe(wire) down.

# data[].attributes.body
electricity is electrons flowing through a metallic object

# data[].attributes.body
the metal atoms are throwing the electrons in one direction like hot potato through the wire

# data[].attributes.body
can only move in one direction

# data[].attributes.body
a circular wire with a battery is a circuit because the electricity is thrown in a circle

# data[].attributes.body
to get electricity in a circuit you need a wire

# data[].attributes.body
it is the result of unbalance between positive and negative charges.

# data[].attributes.body
is the measure of difference between two different chrages.
