Which of the following correctly explains why people should never use electrical appliances while taking baths? a. Water causes electrical cords to fray, exposing your body to live circuits.
How do fuses make using electrical energy safer?
How do fuses make using electrical energy safer? A fuse strengthens electrical wires by binding them together. A fuse opens an electric circuit when the current gets too high. A fuse is a type of insulator that adds resistance to an electric circuit.
Which best describes an electrical current?
An electric current is a flow of electric charge in a circuit. More specifically, the electric current is the rate of charge flow past a given point in an electric circuit. The charge can be negatively charged electrons or positive charge carriers including protons, positive ions or holes.
Which of the following is the best choice for conducting electricity through a circuit?
Copper. One of the most commonly used metals to conduct electricity is copper. As a material, copper is pliable, easy to wrap or solder, which makes it the best choice when large amounts of wiring are needed.
Which of the following describes an electric 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 is the role of fuse wire in our daily life?
A fuse(s) is needed in any electrical system (AC or DC). These protection devices react to the amount of heat being produced by electricity passing through wires and/or components. They are used so as to protect wires and components from the extreme heat produced should there be an electrical overload or short circuit.
Which of the following is the best example of an electrical insulator?
The most effective electrical insulators are: Rubber. Glass. Pure water.
What term best describes voltage?
Voltage, also called electromotive force, is a quantitative expression of the potential difference in charge between two points in an electrical field.
What are 5 good conductors?
Which metal is the poorest conductor of electricity?
Bismuth and tungsten are two metals which are poor conductors of electricity.
Is stainless steel a good conductor of electricity?
Silver is an excellent conductor of heat, while stainless steel is a poor conductor. In fact, silver is twice as good a conductor as aluminum, and nearly 10 times as good as a conductor as low-carbon steel. Copper and gold are the only metals that come close to silver in thermal conductivity.
