Electronics Vocab

What is a circuit?

• A path in which electrons from a voltage or current source flow.

• The rate of flow of electric charge past a point or region.

What is not another word for potential difference?

• Voltage

• Resistance

• Electrical Potential

• Electric Pressure

What is electrical current?

• A unit of electric current equal to a flow of one coulomb per second.

• The SI derived unit of electrical resistance, named after German physicist George Simon Ohm.

• The rate of flow of electric charge past a point or region.

What is resistance?

• A law stating that electric current is proportional to voltage and inversely proportional to resistance.

• A measure of its opposition to the flow of electric current.

What is a transformer?

• A region around a magnetic material or a moving electric charge within which the force of magnetism acts.

• Any device for converting mechanical energy into electrical energy by electromagnetic induction

• A device used to transfer electric energy from one circuit to another

What is a generator?

• Any device for converting mechanical energy into electrical energy by electromagnetic induction

• A device used to transfer electric energy from one circuit to another

• A voltage source is a device (with two ends) that can maintain a fixed voltage

What is the difference between a series and parallel circuit?

• A parallel circuit has one path for electrons and series circuits have more than one path.

• A parallel circuit has more than one path for electrons and series circuits have only one path.

What is an ohm?

• The SI derived unit of electrical resistance

• A unit of electric current equal to a flow of one coulomb per second

What is a magnetic field?

• Each of the two points or regions of an artificial or natural magnet to and from which the lines of magnetic force are directed.

• A region around a charged particle or object within which a force would be exerted on other charged particles or objects.

• A region around a magnetic material or a moving electric charge within which the force of magnetism acts.
