Static Electricity
What is static electricity?
Electricity that stays on the surface and does not flow
What is a conductor?
A material that allows electricity to flow easily
What does a battery do in a circuit?
Provides electrical energy
What symbol shows a battery?
Two parallel lines, one longer than the other
-l┃l ┃-
What is Ohm’s Law formula?
Current × Resistance (V = I × R)
How do you create static electricity?
By rubbing two different materials together
ame one good conductor of electricity.
Copper
What is the purpose of a switch?
To open or close the circuit
What symbol shows a bulb?
A circle with a cross inside ⦻
What unit is voltage measured in?
Volts
Which charge builds up on an object that gains electrons?
Negative charge
What is an insulator?
A material that does not allow electricity to flow easily
What does a resistor do?
It reduces the electric current
What is the job of wires in a circuit?
To connect the parts and let electricity flow
What happens to the current if the resistance increases?
Current Decreases
What happens when you touch something after getting static electricity from rubbing your feet on carpet?
You get a small shock because the extra charge moves to the object you touch
Why do rubber gloves protect you from electric shocks?
Because rubber is an insulator and stops electricity from flowing
What happens to the bulbs if you open a switch in a series circuit?
All bulbs go out because the circuit is broken
In a parallel circuit, what happens if one bulb goes out?
The other bulbs stay on because each has its own path
Explain why increasing voltage increases current in a circuit.
Because higher voltage pushes more electrons through the circuit
