An open circuit is one where the continuity has been broken by an interruption in the path for current to flow. A closed circuit is one that is complete, with good continuity throughout. A device designed to open or close a circuit under controlled conditions is called a switch.
Q. How does a closed circuit work?
When a circuit is complete, or closed, electrons can flow from one end of a battery all the way around, through the wires, to the other end of the battery. Along its way, it will carry electrons to electrical objects that are connected to it – like the light bulb – and make them work!

Q. What is an open circuit answer?
: an electrical circuit in which the continuity is broken so that current does not flow.
Q. What does an open circuit do?
An open circuit implies that the two terminals are points are externally disconnected, which is equivalent to a resistance R=∞ . This means that zero current can flow between the two terminals, regardless of any voltage difference.
Q. What happens after short circuit?
The term short circuit is most commonly used by electricians to refer to the situation in which a hot wire carrying live current touches a neutral wire. When this happens, resistance lessens instantly and a large volume of current flows through an unexpected pathway.
Q. What happens when a series circuit opens?
If the open condition occurs in a series portion of the circuit, there will be no current because there is no complete path for current flow. If, on the other hand, the open occurs in a parallel path, some current will still flow in the circuit.
Q. What is the most common failure in a series circuit?
One of the most common circuit faults in a series circuit is an open.
Q. What happens when there is a short circuit in a series circuit?
this is the case of a short, either a very low resistance or zero resistance. When a short circuit occurs within a series component; others components in the series have higher currents. If this component shorts, the total resistance is going to decrease and so the current in the circuit will increase.
Q. What happens if a resistor is shorted in a series circuit?
A shorted resistor (resistance of 0 Ω) would theoretically draw infinite current from any finite source of voltage (I=E/0). In this case, the zero resistance of R2 decreases the circuit total resistance to zero Ω as well, increasing total current to a value of infinity.
