Question

To maintain a steady current in a circuit what conditions are necessary?

1) Continuous current
2) Development of potential difference
3) Neither (1) or (2)
4) Only (1)

Answer 1

Thank you for asking the question
The important thing that is required to maintain a steady current in a circuit is the development of potential difference. It is the the movement of charges across the circuit from positive and negative terminal and the loss and gain of energy during this process accompanies e movement. This would ultimately increase the potential energy of the charge and leads to the steady floe of the current in a circuit.
Hope it helps.

Answer 2

Answer:

Explanation:

To maintain steady current through the conductor , some external device like source of electromotive force ( cell or battery) must do work at steady rate to take positive charge from lower to higher potential
