An open circuit has a break in it somewhere, so the circuit is not complete and electricity cannot flow. When you power off a light, for example, with an on/off switch, you open the circuit, turning off the light as desired. When there is an unwanted open circuit, for example from a damaged wire, the device or system is unpowered and cannot operate. A short circuit has some unwanted contact between points at different voltage levels, such as from hot to neutral or ground, or between positive and negative. When a short is in a circuit, electricity will take only that path of little or no resistance. The rest of the system is deprived of power, and the conductors feeding the point of the short will likely overheat or burn unless a fuse or breaker operates, creating now an open circuit.

Why bulb not glows when circuit shorts?
There is a concept that one must understand when working with electricity; "electrical current will always take the path of least resistance." Many people don't understand the difference between a "short" circuit and an "open" circuit. An open circuit is when there is effectively no return path from the electrical source back. It's like when a light switch is turned off and the light isn't on. A SHORT circuit would be when the light switch is turned on but another wire is across the same wire pair, resulting in an effectively shorter path between the conductors of the power source. The electrical current then takes the path of least resistance, leaving no electrical current for the bulb. Naturally, there is that gray area between a short circuit and an open circuit, that's where things run properly... in general.
Difference between voltage and emf?
'Voltage' is simply another term for 'potential difference', and an electromotive force is the open-circuit, or no-load, potential difference of a source such as a battery or generator.
What are the safety features available in a breaker?
To detect and open the circuit if a thermal overload is present and to detect and open the circuit if a short circuit caused by a magnetic increase of flux in the circuit.
What is the difference between an open and a short?
An open (circuit) is where insufficient (often zero) current flow where some is expected. In this case, little or no work is done. A short (circuit) is where high (often infinite or as limited by the power supply) current flows where only some is expected. In this case also, little or no work is done by the device intended, but there is enough current to trip (or blow) the protective device (fuse or circuit breaker).
What is a line commutation?
it is the natural commutation ...by making open circuit or short circuit on the thyristor to make it turn off.
What is the difference in an open circuit and a short circuit?
an open circuit is a circuit that does not complete the circle. an open circuit does not do the job as the electricity stands still a short circuit is a circuit that wires have crossed and the electricity takes the shortest path. and does not complete all of the points on the circuit
What is open circuit and short circuit?
Consider two points (A and B) in an electric circuit. An open circuit between A and B means there is no electrical connection between A and B. A short circuit between A and B means there is an electrical connection between A and B.
What is a circuit with no load?
An open circuit or a short-circuit (if that circuit is complete).
What is the difference between a closed and a closed circuit?
closed circuit often called short circuit it means connecting two teminal of a circuit usually plus and minus without resistanace or any component just you have to join open circuit means disconnection between plus and minus dont beak your head for this its easy ma leish habib i!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
When inductor is called short circuit and open circuit?
In DC inductor is short circuited .
What is the design value of short circuit ration of generator?
short circuit ratio is the ratio of field current to open short circuit voltage n the open circuit current. its value for thermal is less than hydro type.

Is there a difference between an open and closed circuit?
In an open circuit, the electrons cannot flow easily because one of the parts in a circuit is not connected, whereas, in a closed circuit all the parts are connected, therefore, the electrons can flow easily. Hope this helps:)
What is the power consumption of the circuit, assuming a short-circuit and an open-circuit between A and BWhich resistance RL can you use such that the power consumption is the average of these two extreme cases?
here is the picture
What are the approximations of open circuit and short circuit tests?
Firstly turn of the power before this test...Using a resistance or continuity tester you should get the following results:Short circuit: Very low resistance (nearly 0 ohms) or the bell will ring.Open circuit: Very high resistance (Somewhere in the range of Mega ohms) or the bell will not ring.The reason for this is because and open circuit has a gap in it (which has high resistance).The short circuit has wires that are crossed and so has a really low resistance.

What is the difference between continuity and resistance check?
Continuity check tests if there is a complete path for electricity to flow between two points, indicating if there is a break in the circuit. Resistance check measures the opposition to the flow of electricity in a circuit, providing information about the quality of connections or components.
