Working of battery in circuit
The battery has a potential difference. So, shouldn't battery generate an electric field directing from the positive side to the negative side? If that's the case, we know that potential in a wire(...

Work done in moving a charge in circuit?
Why is the work done in moving a charge from one point to another in a circuit through any path the same even though heat and other losses are there?

Work done by electric field in a wire
Work done by electric field in moving a unit charge is the potential drop. In wires voltage (potential drop) is given by ohms law. Can somebody explain to me why work done by electric field can not be ...

When talking about potential difference in a circuit, whose work done are we talking about?
I'm asking this because it seems to me that when we talk about PD around a charge (i.e. potential difference between infinity and a point), we're talking about the work done per unit charge by an ...

Why doesn't potential difference across circuit increase when length of wire increases?
Since $V=Ed$, why doesn't the electric potential increase when length of the wire increases. $d$ increases right? Is it because the battery only pushes the electrons from one terminal to the other and ...
