No. Circuit is open but still HOT.

If one of the three lamps blows out when connected in series what happens to the current in the other two?
In a series circuit there is only one path for current to flow. The current will flow through each good lamp. If any lamp opens (blows), then the circuit is broken and current flow stops. The older strings of Christmas tree lights used to be connected in series and it was hard to fine the blown bulb. If there were two burnt out bulbs almost impossible to find.
What happens if a light blows in a parallel circuit?
The rest of the lights in the system will remain illuminated. Except in that branch of the circuit. The parallel branch(s) get more current if the voltage potential remains the same.
What is the best indication of excessive current flow?
The best indication of excessive current flow in an electrical circuit is if a protective fuse blows or a circuit breaker trips.Fuses and circuit breakers are designed to open a circuit when an excess amount of current occurs, so as to break that flow of current.The worst indication of excessive current flow is if a length of cable overheats and/or catches on fire...Equally bad is if a piece of electrical equipment - or its power cord and/or plug - overheats and/or catches on fire...
Why do we use additional rcd for earth fault protection?
A 'standard' fuse requires the current to reach a certain level before it blows. This could theoretically cause a user to suffer an electric shock before the fuse 'blows'. An RCD device monitors the current in the circuit and trips a re-settable switch when the current exceeds a safe level. RCD devices react much quicker than the old-fashioned fuses.
Can home circuits have safety devices called fuses and circuit breakers that close a circuit when too much current passes through?
The safety devices does not close, but opens the circuit. Homes in the United States must have circuit current protection in order to meet building code requirements. They can use fuses or the push-in circuit breakers. In order for amperage to flow through them, they must be closed, which provides a continuous flow of current from the source to the load. If too much amperage passes through, the fuse blows or the circuit breaker opens, creating an open circuit that stops the flow of electricity.
What happens to a fuse when the flow of charges stop?
Current i.e.rate of flow of charge when stops flowing in a circuit then fuse does not blows out. The only work of fuse is to blow away when the current starts flowing greater in magnitude than the rated current value.
What happens in a series circuit if a light blows?
The circuit current is interrupted and all the lights will go out.
What happens when a fuse blows?
When a fuse blows, it essentialy breaks the circuit. So the current can no longer flow, this is used as a safety measure.
Which test can best detect the presence of electrical current a the needle of a compass b the bulb in an electric circuit blows c the plug of an iron is placed in the socket?
Here are some possible answers: a) If you hold a compass close to a wire you may see the needle move. How much it moves depends on the strength of the current flowing in the wire. If the needle doesn't move then there may be three explanations: 1) No direct current was flowing in the wire OR 2) a direct current was flowing but it was too weak to make the compass needle move OR 3) there might have been a current but it was an alternating current changing so fast that the needle did not seem to move. b) If the bulb in an electric circuit was lit but then blows, it may mean one of two things 1) the current was switched off so the bulb went out OR 2) the bulb just died, in which case any current that was flowing in the bulb's circuit would stop. c) when the plug of an iron is placed into a socket, if it warms up then a current must be flowing from the socket to the iron. But before the iron was plugged-in, no current was flowing. Now you work out which of those answers to this question is the right one!
How can a fuse stop the current flowing if the currents to big?
it gets broken A fuse is specifically designed so that when the current exceeds its specified rating, the fuse itself fails in some way (usually, part of it melts or burns out). When the fuse "blows", the circuit is cut open, so current can no longer flow.
Why does a fuse blow?
A fuse blows when the current draw of the circuit is greater than the capacity of the fuse.
Why does the my dodge mini van engine fuse blows out?
The current flow in the circuit has extended the rating of the fuse.
When a fuse blows does the circuit short out?
Not necessarily. It can blow because the circuit was overloaded and pulling too much current. That would cause the fuse to overheat and blow.
If one of the three lamps blows out when connected in series what happens to the current in the other two?

What is the problem when a fuse blows on a 2001 Chrysler Town and Country?
A fuse blows when there is a short circuit or an overload in the circuit.
When fuse blows?
When a fuse blows, you should replace the fuse and check to see what might have caused it to blow. It's a sign that there might be something causing too much current to flow in the circuit.
What will cause your engine main fuse to blow?
A fuse blows when the circuit is drawing too much current. It could be a short or an overload.
