When the conductor between two contacts is a non-conductive material such as air, the circuit is open. WHen the conductor between two contacts is a conductive material such as graphite or ferrous metal, it is closed.
A: Because it has no connection or open as we say
An open circuit is characterized by a break in the conductive path, resulting in infinite resistance. Therefore, it is not accurate to say that an open circuit has a resistance of less than 250K ohms; it effectively has a resistance that is much greater. In practical terms, an open circuit behaves as if it has no current flow due to this infinite resistance.
An open circuit is called open because the circuit has an opening, a disconnection. In other words, there is an open space in the circuit in which the electrons cannot move through.
An open circuit....
When a circuit is in off condition then it is called an open circuit..
As load is conected in circuit , so thre is no open circuit therefore there would not be any open circuit voltage.
If the circuit was open, the tram's motor could not run!
meaning that the current from your power source doesn't return to the positive end (electricity flows from - negative, to + positive)
When a plug key is open , the circuit is incomplete and is call open circuit.. To be continued..
a circuit which is open
If the lights are the load of the circuit, then the lights will be off if the circuit is open.
An open circuit or a short-circuit (if that circuit is complete).
