Quiz
the electronic potential and force whose measurement unit is volts
tensão, voltagem
an electrical component designed to limit or control the flow of electric current in a circuit, typically by providing resistance
resistor, resistência
the complete circle through which an electric current flows, typically consists of the source of electric energy
circuito elétrico, circuito
a solid substance that conducts electricity or heat better than insulators, but not as well as most metals
semicondutor, substância semicondutora
a phenomenon where certain materials conduct electricity without resistance when cooled to extremely low temperatures
supercondutividade, supercondutância
to apply an electric charge to a conductor
eletrificar, eletrocutar
a conductor through which electricity travels to or from an object, such as batteries

an area of technology that is concerned with the study or use of robots
robótica, tecnologia de robôs
(physics) the increase in velocity over time
aceleração, aceleração linear
the constant speed reached by a falling object when the drag force equals the gravitational force pulling it downward, resulting in no further acceleration
velocidade terminal, velocidade de queda livre
relating to the transmission or control of fluids under pressure within confined systems or machinery
