COLUMN 1
The standard unit used to measure how strongly an electrical current is sent around an electrical system.
What is a VOLT?
The ability to do work.
What is POWER?
The SI base unit of electrical currents.
What is an AMPERE?
A force that pushes and pulls the current (energy) through the circuit that make charges flow.
What is a VOLTAGE?
A unit of electrical resistance.
What is an OHM?
A rotating machine that transforms electrical energy into mechanical energy.
What is a MOTOR?
A basic component of electric circuits designed to resist the passage of current flow.
What is a RESISTOR?
An object or type of material that allows the flow of charge (electric current) in one or more directions.
What is a CONDUCTOR?
A device that transforms mechanical energy into electrical energy.
A material that does not allow charge or electricity to pass through.
What is an INSULATOR?
When a current follows only one path from the positive end of the battery toward the negative end.
What is a SERIES CIRCUIT?
A soft metal core made into a magnet by the passage of electric current through a coil surrounding it.
What is an ELECTROMAGNET?
A way of connecting electrical components on separate branches, so that the current divides and flows through different paths.
What is a PARALLEL CIRCUIT?
The process of producing an electric current or a magnetic property in an object by placing it near another object that has an electric current or a magnetic field.
What is an INDUCTION?
This represents the "total effect" of all resistors in a circuit.
What is EQUIVALENT RESISTANCE?
A region around a charged particle or object within which a force would be exerted on other charged particles or objects.
What is an ELECTRIC FIELD?
Refers to the amount of work or energy involved in moving an electric charge from one point to another.
What is a POTENTIAL DIFFERENCE?
An electric current flowing in one direction only.
What is a DIRECT CURRENT?
A vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.
What is a MAGNETIC FIELD?
A device that transforms voltages from primary to secondary.
What is a TRANSFORMER?
The production of an electromotive force across an electrical conductor in a changing magnetic field.
What is an ELECTROMAGNETIC INDUCTION?
A region within a magnetic material where the magnetic moments of the atom are aligned with one another and point in the same direction.
What is a MAGNETIC DOMAIN?
An electric current that periodically reverses direction and changed its magnitude continuously with time.
What is an ALTERNATING CURRENT?
A region at each end of a magnet where the external magnetic field is strongest.
