Incorrect answer
Then only one of the lights go out.
Correct answer
Actually ALL the lamps will go out if a short circuit occurs across any branch of a parallel circuit because, if the wiring has been done correctly, a circuit breaker will trip or a fuse will blow to cut off the supply of current to all the lights.
The loss of a single lamp indicates a break, not a short circuit.
What else can I help you with?
When you short out a resistor in a parallel circuit why does the current lower?
The total resistance of a set of resistors in parallel is found by adding up the reciprocals of the resistance values, and then taking the reciprocal of the total. By removing a resistor the total current will lower. If you short out the parallel circuit as suggested it will take out the fuse that should be protecting the circuit.AnswerShorting-out a resistor in a parallel circuit, will act to short out the entire circuit, therefore, significantly increasing, not lowering, the current! And, as the previous answer indicates, this short-circuit current will operate any protective devices, such as a fuse.In a parallel circuit current does not lower but it will be increase if shorting-out one resistor in the two resistor parallel circuit, the circuit will become very low resistive and the larger current will flow through the short path.
If a parallel circuit shorts at the battery will the entire circuit short out too?
If at battery,parallel circuit shorts then equivalent resistance of circuit becomes approximately 0 Ohms,and therefore as current follows low resistance path infinite amount of current due to low resistance will flow through the wire so,entire parallel circuit will short out,but wire will burn and battery may get damaged.

In parallel circuit-what happens to the total resistance if one branch opens-Provide an example?
Increases
Is the current pass through parallel short resistance?
no.because current always try to flow trough low resistance path.as short circuit has low resistance current pass trough short circuit
Each branch in a parallel circuit may hold several resistors yes or no?
No. What you are describing is a series-parallel circuit, not a parallel circuit.
What type of circuit are there?
parallel circuit / series circuit / and a short circuit
What happens to the total resistance in a parallel circuit with a short?
In case of parallel circuit the effective resistance is given by Reff = R1*R2*R3 /(R1R2 +R2R3 +R3R1) As short circuit takes place then anyone R1,R2,R3 becomes zero. Hence Reff becomes zero.
What happens to resistance when resistors are wired in parallel delta circuit?
What do you mean by a 'parallel delta' circuit -is there such a connection.

If you unscrewed the second bulb in the parallel circuit when it was on what happens to the first?
Nothing. That's why it's a parallel circuit. If it was a series circuit, then the first bulb would go out.
What happens if the switch is open in a parallel circuit?
If the switch in a parallel circuit is open, it breaks the circuit and interrupts the flow of current for that particular branch. The other branches in the parallel circuit remain unaffected and continue to operate independently.
How can an ammeter cause a short circuit?
An ammeter can cause a short circuit if it is connected in parallel instead of in series with the circuit being measured. This can create a low resistance path for the current to flow, bypassing the intended circuit and causing a short circuit.
What happens if there is a break in parallel circuit?
If the break is in either the feeder or return line, the circuit will become open and the circuit will cease to function.
What happens to the current in the series circuit?
current remains same in series while divide itself in parallel circuit
What are the two kinds of electrical circuit?
There are four types of circuit: series, parallel, series-parallel, and complex.
What happens when a part of a parallel circuit is disconnected?
current decreases and resistance increases
What happens if a wire breaks?
The circuit stops working because of the short circuit
