Question

what is a closed and open circuit

Answer 1

An open circuit obstructs the flow of current whereas a closed circuit allows the current to flow thr. it. A short circuit is like a wire -- there is no change in voltage across the short.

An open circuit is like a wire that is cut -- voltages on either side of the open circuit are independent of one another.

Answer 2

If any part of a circuit is broken,electric current does not pass through it,such a circuit is called open circuit.

If there are no breaks in the circuit,it provides a closed path for electric current to flow through and such a circuit is called closed circuit.
