Module 19: Electric Current and Circuits

Horizontales
An automatic switch that opens when the current through an electric circuit exceeds a threshold value.
A device with a specific resistance; may be made of long, thin wires, graphite, or semiconductors and often used to control the current in circuits or parts of circuits.
A device made up of several galvanic cells connected together that converts chemical energy to electrical energy.
A closed loop or pathway that allows electric charges to flow.
A type of electric circuit in which there is only one current path and all current travels through each device.
An unintended, very low-resistance circuit that results in a very large current, overloading wires and potentially breaking electrical components and starting fires.
A device that contains an electronic circuit that detects small current differences caused by an extra current path.
A type of connection in which there is only a single current path.
The direction in which a positive test charge moves.
A series circuit that is used to produce a potential difference source of desired magnitude from a battery with a higher potential difference.
Verticales
A type of connection in which there are two or more current paths to follow.
A flow of charged particles.
The value of a single resistor that, when it replaces all the resistors in the circuit, results in the same current.
A material with zero resistance that can conduct electricity without thermal energy transformations.
A short piece of metal that acts as a safety device by melting and stopping the current when too large a current passes through it.
The measure of how strongly an object or material impedes the flow of electric charge produced by a potential difference.
A flow of electric charge, or electric current, equal to one coulomb per second.
