Answer to your question in one word is "no" To clarify further we may split the question into two parts 1) Do you think there will exist a electric potential difference(between +clamp and earth)? Answer is "yes" 2) Can the above potential difference be measured by voltmeter? Answer is...

Case 1: Dipole distribution is correct Case 2:Electric field distribution changes when load current flows. When there is no load current and the circuit is open, surface charge distribution on the conductors connected to DC source is such that there is no electric field inside the conductor...

I think there is some thing wrong with your understanding of battery.Do you think that, initially all the carrier electrons needed for conduction are accumulated at anode with some potential energy,which are inturn emitted and circulated through out?

Transient state is, as you said, when the battery is connected to the circuit through switch.Then the following events occur 1) Charges(electrons) start moving throughout the circuit 2) Due to charge separation caused by battery, some parts of the circuit start accumulating negative surface...

I will try to explain it in another way..In the transient state ,electrons acquire the required kinetic energy they need in the steady state.What battery does during steady state is to supply exactly the 'extra' potential energy needed for the electrons to overcome the resistance.This 'extra'...

It depends on the reference direction you chose.If you considered a load,and the reference direction of current is entering towards positive reference terminal of load voltage you will not get an angle more than 90 degree, and the active power(absorbed) is always positive.However for a power...

The surface charge variation depends on the shape of conductor.It also gets affected by the bends present in the conducting wire.In anycase, during steady state they align in such a way to produce the required electric field.If the conductor is cylindrical with uniform cross section and zero...

Yes.It is the movement of electrons from an area of higher surface charge density(more negative) to lower surface charge density(less negative) causes potential drop If the wire is superconductor, then the surface charge density is uniform even when current is flowing.This is analogous to a...

Field definitely acts on a conductor which is far away.But if there is no closed circuit the charges in the far away conductor align and reaches equilibrium.This means the surface charges in the far away conductor are aligned and cancels out the electric field inside.However if the conductor is...

I have attached the figure provided in the textbook, "Matter and Interactions" Figure shows the interface between a copper conductor and a carbon resistor during transient.Electron flow is from right hand side to left hand side, given as green arrows.In the initial transient, before steady...

Let me share my understanding about how electric field works in circuits ,what a voltage source does and what happens inside resistor as well as conducting wires. Consider the 9V battery as shown in the circuit diagram.Assume that the circuit is open.The function of battery/dynamo or any voltage...

Unable to open the second link.I guess, your question is related to this document

Batteries are not like charged capacitors.Hence the explanation cannot be based on drain of charges when we connect a small resistance across it. Batteries or any other voltage source generates voltage through charge separation, i.e pushing positive charges to one terminal and negative to...

In the case of AC , opposition to the current flow depends also on the frequency involved.Every conductor, whether super conductor or not, will have a non zero self inductance.This means the conductor is linked by its own flux.When a time varying current flows, the resultant time varying flux...
