Basic Concepts
The term for the measure of electrical pressure which is pushing the current through a circuit.
What is voltage?
When components are arranged in a single loop such that the current passes through each component after the last.
What is a series circuit?
A magnet that is created by passing an electric current through a coil of wire.
What is an electromagnet?
This is the term used to refer to a magnet that keeps its magnetic properties for a long period of time
What is a permanent magnet?
This is what AC stands for.
What is alternating current?
A conductor does this and an insulator does not.
What is conduct or allow electrons to flow freely?
When current is not able to flow through a circuit.
What is an open circuit?
A device which converts electrical energy into kinetic energy
What is a motor?
An iron-bearing material must have this to be magnetized.
What are aligned domains?
This is what DC stands for.
What is direct current?
This thing converts chemical energy into electrical energy.
What is a battery.
This thing allows a circuit to be opened or closed with ease.
What is a switch.
The force field that surrounds a magnet or a conductor carrying an electric current.
What is a magnetic field?
This device uses electricity to spin a coil inside of a magnetic field.
What is a galvonometer?
This type of current traveled through the circuits in your labs.
What is DC?
The measure of how difficult it is for electric current to flow through a material.
What is resistance?
This safety device breaks the circuit when the current flowing through it exceeds a certain level.
What is a fuse or circuit breaker?
A device that converts mechanical energy into electrical energy.
What is a generator?
The south pole of a permanent magnet will be attracted to this pole of another magnet.
What is the north pole?
When 13 volts AC enters a transformer on one side, and the other side has twice the number of coil wraps, this is the resulting voltage on that side.
What is 26 volts?
What is a circuit?
A circuit where the components are arranged in separate branches such that the current divides and flows through each component independently. (Lots of open lanes)
What is a parallel circuit?
This device converts AC from one voltage and current to another.
What is a transformer?
This is the region around a magnet where the magnetic forces act.
What is the magnetic field?
This is the AC voltage that can be found from USA's wall outlets.
What is 120 volts?
