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

Expert Solution & Answer

To determine

To explain:

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

Explanation of Solution

Introduction:

Current in any conductor is the flow of electron within it.Kirchhoff first law which is based on current at any nodemust be zero. If electron flow within anybody, then total charge at any particular point must be zero

For electric current to flow in conductor there must be a flow of electrons within the conductor. As electrons are negatively charged particle and amount of current flow in a conductor is determined by the flow of electrons. But when electron carried from battery to conductor it must be entered through one terminal and then passes to the other terminal of the battery. So, the charge does notremain in conductor it passes to the battery that is the reason for conductors have a neutral charge.

Conclusion:

Thus, the wire hasa neutral charge if current flow through it due to the conservation of charge at all point of wire.

Students have asked these similar questions

The current is zero in a conductor when no potential difference is applied because: otherwise Ohm's law would not be valid. the electrons are not moving. the electrons are not moving fast enough. for every electron with a given velocity there is another with a velocity of equal magnitude and opposite direction. equal numbers of electrons and protons are moving together.

Which conductor would have the greatest resistance to the flow of charge entering from the left? Which would offer the least resistance? Explain the reason.

Your desk lamp draws a current of 0.20 A for 500 s. How much charge fows through the lamp in this time? How many electrons fow through the lamp in this time? [Answer: (a) ∆Q = 100 C,(b) N = 6.3 × 1020 electrons]
