What carries electric current the best?
MetalsMetals like copper, silver and gold are very good conductors of electricity, that is, electrons may flow freely in those and most other metals because of how electrons are arranged around their nuclei. Other materials, like most plastics and ceramics, glass, rubber and teflon behave in the opposite way.
What is this tool shown Asvab?
The tool pictured is a hole cutter bit, also known as a hole saw.
What can be used to store an electrical charge?
Capacitors are devices which store electrical energy in the form of electrical charge accumulated on their plates. When a capacitor is connected to a power source, it accumulates energy which can be released when the capacitor is disconnected from the charging source, and in this respect they are similar to batteries.
Which type of circuit is circuit a?
DissimilaritiesCircuit In SeriesCircuit In ParallelThere is a single current pathwayThere are multiple current pathwaysAll components have similar current running through themAll components have similar potential difference across them1 more row
What is current circuit?
electric circuit, path for transmitting electric current. An electric circuit includes a device that gives energy to the charged particles constituting the current, such as a battery or a generator; devices that use current, such as lamps, electric motors, or computers; and the connecting wires or transmission lines.
What does AC stand for quizlet?
Alternating Current. The abbreviation AC stands for. You just studied 28 terms! 1/28.
What does AC stand for Asvab?
5.0. 4 Reviews. what does the abbreviation AC stand for. alternating current.
Which device restricts current flow to single direction?
A diode is a semiconductor device that essentially acts as a one-way switch for current. It allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction.
What device reduces current flow?
ResistorA Resistor is a device which opposes the flow of charge in the circuit. Hence it is used to limit electric current flow in the circuit.
What is the most common circuit control device?
SwitchesSwitches are the most common control device for electrical circuits. Switches operate a circuit by opening or closing the circuit. Switches are operated manually, hydraulically, electrically, or pneumatically.Sep 11, 2021
What is a capacitor device?
capacitor, device for storing electrical energy, consisting of two conductors in close proximity and insulated from each other. A simple example of such a storage device is the parallel-plate capacitor.
