circuits
What is circuit?
A pathway for electricity to flow; must contain a power source, a pathway, and a load
What is a conductor?
An object which allows the flow of electric current
What is energy?
the ability to do work
What is a closed circuit?
A complete circuit; allows the flow of electricity
What is an example of a conductor?
metals, steel, cooper
aluminum nail
steel screen
What is an electron?
The part of an atom with a negative charge which circles the center of the atom; can jump from one object to another; can flow through a circuit
What is an open circuit?
A circuit with a gap; does not allow the flow of electricity
What is an insulator?
An object which does NOT allow the flow of electric current
What is static electricity?
Electricity caused by electrons jumping from one item to another
What is a parallel circuit?
A circuit with more than one pathway for electricity to flow through;
lights more than one bulb brightly;
if one bulb goes out, the others continue to work
What is an example of an insulator?
plastic, wool, wood
popsicle stick
rock
plastic chip
yarn
What is an example of static electricity?
lightning or the electric shock when you touch a doorknob
What is a series circuit?
A circuit with one pathway for electricity to flow through;
lights shine less brightly;
if one bulb goes out, the others will no longer work
What type of materials allows a bulb to light in a circuit?
conductors or insulators
Conductors
What is a switch?
A component which controls the flow of electricity in a circuit (opens and closes a circuit)
