It is the measurement of the rate of electrical energy in a circuit. More specifically the electric current is the rate of charge flow past a given point in an electric circuit. An electrolyte conducts an electric current as a solid and does not dissolve in water.

It is the energy produced by protons. Which statement best describes how an electric current affects a compass. It is the energy that moves through wires.

North Carolina Testing Program EOC Physical Science Sample Items Goal 4 Page 11 Published January 2008. B Resistance is the force that drives the current. Current I tq.

Which of the following terms best describes an electrical current. A complete path from high voltage to low voltage through which electric charge can flow. Current is defined as the rate of flow of charged particles mainly electrons in a particular direction through a conducting medium and is measured in Amperes.

Because static electricity is not. It limits the amount of electrical energy that can pass through a circuit. It is the flow rate of electric charge through a conducting medium with respect to time.

In formulas using the symbol I or i. C The electric current makes the compass needle move. Which word best describes electricity as it occurs in nature.

First it is the energy supply. B An electric current is an electromagnetic wave produced by a movement of electrons from the negative terminal to the positive terminal C An electric current is a flow of electrons along a conductor from the positive terminal to the negative This problem has been solved. The charge can be negatively charged electrons or positive charge carriers including protons positive ions or holes.

Because all energy is released at once in static electricity. According to Ohms law electric current can be given by voltage divided by resistance of the circuit. The rate of flow of charged particles through a conducting medium.

If an alternating voltage is applied on the capacitor a displacement current passes through the capacitor irrespective of the insulating medium. Answer choices A flow of protons A flow of atoms A flow of electrons A flow of neutrons Question 8 30 seconds Q. It is the energy produced by protons and neutrons.

This current is termed also the capacitive current. Which of the following best describes current in the context of electricity. Ajt produces electric charges DIt is the same as electric charge Cit is produced by moving positive charges dit is produced by moving hegative charges 2.

C Current is a unit of measurement for resistance. Electric current is defined as the flow of electric charges. D Both cause electricity to flow through a circuit.

It is the amount of electrical energy that is available in a circuit An electric circuit has an expected current of 80 amps. It describes how much electrical energy passes in a circuit. Electric current is defined as a stream of charged particlessuch as electrons or ionsmoving through an electrical conductor or space.

The driving force for electrical flow. A Electrical Current B Electrical Current C Electrical Current D Electrical Current. The tendency for a material to oppose the flow of electrons changing electrical energy into heat energy and light.

Because electrons arent transferred in bursts of static electricity. It is denoted by letter A. A The electric current goes from the wire into the compass.

A An electric current is a flow of molecules along a conductor. It is the energy produced by moving electrons. The flow of electronsElectric current is the rate of charge or flow past a given point in an electric circuit.

An electric current is a flow of electric charge in a circuit. B The electric current works only with thin copper wire. Why is static electricity not useful as a power source.

A closed path that electric current follows answer choices Voltage Current Resistance Circuit Question 2 120 seconds Q. Technician A says electronic circuits use less amperage and often process electrical signals rather than perform the work of lighting heating and mechanical movement. The flow of current is same in all the components which are connected in series.

Second the energy supplied by the battery is required to do work upon the charge to move it against the electric field from the negative terminal to the positive terminal. Technician B says electrical circuits usually conduct higher amounts of current through heavier conductors and commonly operate high current flow devices such as. When an electrolyte dissolves in water the resulting solution conducts an electric current.

Which statement describes an electrolyte. The movement of electrons. Up to 24 cash back What best describes the relationship between current and resistance in DC circuits.

Mathematically it is given by. Which statement best describes what electric current is. The parameter measured in units of volts.

The material property that inhibits electricity flow in. 600 500-R Wr W-W 300. Which graph best describes the relationship between magnetism and electrical current.

The unit of current is amps or amperage and 1 ampere 1 coulombsecond. Answer choices Voltage Current Resistance Circuit Question 3 120 seconds Q. T time interval.

What best describes the term electric current. V A hey are inversely proportional to each other. D The electric current causes the nail to swing near the compass.

Electricity cannot pass through them at all Solar energy can pass through them but electric current cannot Question 7 30 seconds Q. It is denoted with the symbol I. Electric current is expressed mathematically eg.

The current is defined as it is the rate of flow of electric charge in a circuit. Science Physics QA Library Which of the following best describes a conventional electric current. May reproduce for instructional and.
