Circuit which gives continuously varying potential is called _______________________?
Correct answer: C. potential divider
- A. complex network
- B. wheat stone bridge
- C. potential divider
- D. all of above
Explanation
A potential divider uses series resistors to provide an adjustable fraction of the supply potential, giving a continuously varying output voltage. Option b, Wheatstone bridge, is mainly used to compare or measure resistance and is not the general name for this arrangement.

About Steady Current
Steady current is the continuous flow of charge at a constant rate through a conductor. The topic covers current, charge, potential difference, resistance, Ohm's law, resistivity and electrical power, along with series and parallel circuits, while distinguishing conventional current direction from electron motion.
