Electric Charges and their movement
This subatomic particle flows through the wire when an electric field is present.
What is an electron?
This is the object that closes and opens the current in a circuit.
What is a switch?
This is a measure of the amount of electrical energy transferred by an electric charge as it moves from one point to another in a circuit.
What is voltage?
The ______ particles in storm clouds tend to gather at the top of the cloud while the ________ particles tend to gather at the bottom of the cloud.
What is positive and negative?
This is a path in which electric charges can flow.
What is an electric circuit?
This is the SI unit of electric current.
What is an amp?
Every magnet has two of these.
What are magnetic poles?
This is a movement of a static charge from from place to another.
What is static discharge?
Three components of a circuit.
What is a wire, battery, resistor, switch, light bulb?
A circuit that has more than one path to follow.
What is a parallel circuit?
This is a current carrying wire wrapped around an iron core.
What is an electromagnet?
This is an imbalance of electric charge (-) on an object
What is static charge?
Name at least 2 examples of insulators that can slow the flow of electrons in a circuit.
What are wood, plastic, styrofoam, glass and rubber?
In this circuit, devices are connected so there is only 1 closed path for current to follow.
What is series?
This might cause magnets to oppose one another.
What is they have the same charge?
These are the two ways an object can be charged.
What is charging by contact & charging by induction?
This is the difference between a fuse and a circuit breaker.
What is a fuse has to be replaced but a circuit breaker just needs to be flipped back on?
This is a circuit where there is more than one close path for a current to follow. If one bulb goes out this happens to the other bulbs in the circuit.
What is they stay lit up and equally bright?
The place where a magnet is the strongest.
What is at both poles?
