Question

Two conductors A and B are joined by a copper wire. State the direction of flow of electrons in each of the following cases-
(i) If A is negatively charged and B is positively charged (ii) If B is uncharged and A is positively charged (iii) If A and B are both negatively charged with qA ≥ qB What is the work done in moving a charge of 90 C through a potential difference of 30 V?​

Answer 1

Answer:

The electrons are negatively charged particles and so, the electrons move towards the positively charged conductor A. Hence, the direction of the flow of electrons in the copper wire is from B to A.
