Circuit Basics
What is a circuit?
Answer: A closed loop that allows electric current to flow.
What is a resistor?
Something that resists the flow of electric current
In a parallel circuit electricity has ______ path(s) to follow.
multiple
What is electric current?
flow of electric charge
Name a common use for circuits in everyday life.
Circuits are used in household appliances, such as toasters and microwaves
What is the difference between a closed and open circuit?
An open circuit doesn't allow current to flow, and closed circuit does.
What is the purpose of a battery in a circuit?
It is the electrical source needed to get current flowing.
If one load stops working in a series circuit what happens to any other loads in the circuit?
They also stop working.
What is Voltage?
electrical potential difference between two points
how do circuits power a light bulb?
Current flows through the filament in the bulb producing light when it heat up
Name two types of circuits
Series and Parallel
Define what a conductor is.
a material that allows electric current to flow easily through.
Do you think Christmas Lights are an example of a series circuit or a parallel circuit? why do you think that?
They are an example of a series circuit because if one of the bulbs burns out the entire strand will not light up.
Explain the relationship between voltage and current
as voltage increases, current increases if resistance remains the same.
What is a series circuit?
a type of circuit where components are connected end to end
What is a circuit diagram?
A visual representation of an electrical circuit using symbols
Define the function of a switch in a circuit
it controls the flow of the circuit
Draw a diagram of a parallel circuit
Pending Answer
What is the unit to measure current?
Ampere ( Amps )
What is a parallel circuit?
a type of circuit with multiple pathways for current to flow
Explain Ohm's Law
V=CR
Name a load that can transform electric energy into thermal energy and name another load that can transform electric energy into sound energy.
Thermal- lightbulb, heater, etc. Sound- radio, speaker, phone, computer etc.
Draw the symbols for battery, light bulb, and a switch
Answer pending
How does resistance affect the current flow?
Higher resistance decreases the flow of current, while lower resistance increases it.
How are circuits used in computers?
They process data, store information, and control operations
