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.

If you unscrew the second bulb in a series circuit while the batteries are in a parallel circuit what happens?
The first lamp will go out. ANSWER: any lamps in series the first or the last if unscrewed will cause all lamps to extinguish no matter whether the source potential is in series or parallel
If you unscrewed the second bulb in the series circuit when it was on explain what happens to the first?
Unscrewing any bulb in a series circuit turns them all off. This is the same as opening the switch that controls them.
What are trhe advantages of parallel circuits?
One of the parallel circuit focal points is that it guarantees all parts of the circuit have the same voltage as the source. Case in point, the second or each extra light added to the circuit would have the same shine.
What happens in a series circuit if the resistance is halved?
If you add a second resistor, the resistance of series circuit will increase.
What happens to the current in circuit as the resistance increases?
Current decreasesWhen voltage remains constant and resistance increases the current in the circuit will reduce.More informationV=IRwhere V is voltage,I is current andR is resistance.From the above equation,R=V/I, and hence resistance is indirectly proportional to current.Therefore, an increase in resistance would have the effect of decreased current.NB: this holds true only as long as the voltage remains constant.Another opinionHowever, this is only true in the case of a circuit connected in series.When circuits are connected in parallel, the opposite happens. If there is an increase in the amount of resistors in parallel, the total resistance of the circuit then decreases and the current increases subsequently.Yet another viewNo, that's not stated right.If more resistors are added in parallel - so that the circuit's overall total resistance decreases and its total current increases - that is NOT in any way the opposite of what this question is asking about...Let's make this crystal clear, so that there is no confusion: "an increase in the amount of resistors" is NOT the same as "an increase in resistance".So a parallel circuit behaves EXACTLY the same as a series circuit: if its overall resistance increases, the overall current going through the parallel circuit decreases AND if its overall resistance decreases, the overall current going through the parallel circuit increases.Actually, the second opinion is correctIn a parallel circuit, there are more branches to allow electrons back to the power supply, so current increases. With more resistors in a circuit, the overall resistance in a parallel circuit DECREASES.In a series circuit, current is the same throughout. So if more resistors are added, resistance INCREASES and so current DECREASES.
If an electric current is flowing through a parallel circuit which units tell you about the amount of electrons traveling in the circuit?
It makes no difference whether the circuit is parallel, series or complex. The number of electrons travelling (or oscillating back and forth for AC) is determined by the current (amps). 1 amp = 1 coulomb/second. 1 coulomb = the charge represented by 6.24150962915265 x 1018 electrons. The current in each leg of a parallel circuit has to be worked out separately.
What happens to the brightness of the bulb when the second bulb is put into a series circuit?
it should become dimmer
What are parallel circuits and series circuits?
Parallel and Series circuits are the two simples ways of connecting and composing an electrical circuit or electronic circuit. The difference is that the series circuit consist of one single path of electronic flow - where in if one is switch off, all of the remaining switches will be turned off as well. While the parallel circuit consists of two paths - where in even if the other path is swtiched off, the second path won't be wit the stopped flow of electricity.
How do you know if you have a series circuit or parallel?
A series circuit will be wired from the power source at the positive input of the first device, the second device will receive power from the output of the first device and then go back to ground. A parallel circuit is wired so that both devices receive power from the power source directly to the positive input and both are wired directly to ground.
What happens when you replace a wire in a circuit with a piece of string?
Well, you have almost invented the string can telephone!! Keep at it..second answer since ordinary string is not a conductor, you no longer have a circuit. Remember a circuit is a continuous path.
What are the differences between a parallel circuit and a series circuit?
in parallel circuit passive components such as resistor capacitor and inductor are connected in such away tht all components positive sided terminals are connected together and similarly negative sided terminals. and then positive terminal of the source is connected to positive side and vice versa.while in case of series circuit negative terminal of first component is connected to the positive terminal of the second component and so on and then source is connected
What changes occur in the total resistance of a circuit as additional resistances are added in parallel?
The total resistance of the circuit increases. hence the new resistance after adding the resistance will be new resistance = old resistance + added Resistance There is a small mistake in the question. The second word is 'changes' not 'charges'
