Question
There is a positively charged sphere A and negatively charged sphere B, such that they are brought in electrical contact by a copper wire.
In which direction conventional current flows?
Solution
Sphere A is positively charged and sphere B is negatively charged.
Both spheres A and B are brought in electrical contact by a copper wire.
Conventional current flows from sphere A to sphere B i. e. from a body at higher potential to the body at lower potential.
