Electricity Flashcards
What is current
Where electrons flow past a point to create an electrical circuit.
Define electrical circuit
A complete path where electric charge can flow.
Explain the difference between parallel and series circuits
A parallel circuit is an electric circuit providing more than one conducting path. A series circuit is an electric circuit with one conducting path and that current passes through each element without branching.
What is a conductor? What types of materials are good conductors? Why?
A conductor is something that charge moves easily through. Some materials are metal, copper is one of the best, people, water. Charge moves very easily through all of these.
What is an insulator? What types of materials are good insulators? Why?
An insulator is something that charge cannot move through. Rubber, plastic, glass, and wood are all good insulators.
What is electricity
the flow of electrons
What is a battery
a device that stores chemical energy and turns it into electrical energy.
What is resistance
A measure of the opposition to current flow in an electrical circuit
What is static electricity
a build up of charge on an object
What is static discharge
The loss of static electricity as electric charges object.
What is the difference between AC and DC?
AC’s, alternating current, flow changes directions constantly and DC’s, direct current, flow goes one direction.
Explain the difference between electric current and static electricity.
Electric current is caused by the movement of charge or electrons. Static electricity is caused by charge at rest on the surface of an object.
What is a proton and where is it located?
A proton is a positive charge and it is located in the center of the nucleus of an atom.
What is an electron and where is it located?
An electron is a negative charge and it is located either bound or not bound to an atom.
What is the law of conservation of charge?
In a closed system the charge will remain constant.
