I have read that the FLOW OF ELECTRONS is called electricity. I wanna know that what is meant by flow of electrons? Pleaz answer me….
(Asked Kiruthika)
Answer:
Electric current is the flow of charges.
The mechanism of operation in a capacitor
The DC doesnt flow through capacitor. I thought it was because the electrons jus get saturated on one side and are lost on other side, such that it can’t take or give up anymore or plausibly due to voltage developed across it whereas in AC as directions keep changing, saturation doesnt occur. But it if [...]

Is potential difference is directly proptional to resistance?
Is potential difference is directly proptional to resistance? (atanu asks) Answer: For a constant current, the potential difference is directly proportional to the resistance included in the circuit. For a given conductor at constant temperature, resistance is a constant and the potential difference across it is directly proportional to the current passed through it.
