Can a wire carry a current and still be neutral - that is, have a total charge of zero? Explain.

Short Answer

Expert verified

No. If there's a regularcutting-edge or no cutting-edge, the cord is usually neutral.

Step by step solution

01

Definition of current and neutral

A flow of electrical charge carriers, usually electrons or electron-deficient atoms, is called current.

A neutral particle, such as a neutron, is a particle that has no electric charge in physics.

02

Explaining a wire can carry a current and still be neutral- that is, have a total charge of zero

The quantity of electrons that input the twine is the sameasthe number of electrons that go outof it.Despite their continuous movement, the internet quantity of electrons inside the twine is regular. If the quantity of electrons is usuallyregular and the sameas the number of protons, then the sum of all rates is the sameas zero, or in different words, the twine is neutral.

Foolishly trying to fish a burning piece of bread from a toaster with a metal butter knife, a man comes into contact with \({\bf{120 V AC}}\). He does not even feel it since, luckily, he is wearing rubber-soled shoes. What is the minimum resistance of the path the current follows through the person?

A charge of \(4.00{\rm{ }}C\) charge passes through a pocket calculator’s solar cells in \(4.00{\rm{ }}h\). What is the power output, given the calculator’s voltage output is \(3.00{\rm{ }}V\)? (See Figure \(20.40\).)

In this problem, you will verify statements made at the end of the power losses for Example \(20.10\). (a) What current is needed to transmit \(100{\rm{ }}MW\)of power at a voltage of \(25.0{\rm{ }}kV\)? (b) Find the power loss in a \(1.00{\rm{ }} - {\rm{ }}\Omega \) transmission line. (c) What percent loss does this represent?

Why do incandescent lightbulbs grow dim late in their lives, particularly just before their filaments break?

(a) Referring to Figure \(20.34\), find the time systolic pressure lags behind the middle of the QRS complex. (b) Discuss the reasons for the time lag.
