What happens to the total current provided by the battery as more bulbs are added to a parallel circuit?
The total current increases in this case.
How is resistance affected as more branches are added to a parallel circuit?
in a parallel circuit, the relationship of resistance is thus: 1/R1 + 1/R2 = 1/RT where R1 and R2 are two resistors in parallel and RT is the total resistance in the circuit: Using this, as more branches are added, the resistance decreases This is because there is more ways for the current to flow and thus using the analogy of a water flow with a constraint on it (resistor in electrical circuits), a whole load of streams with the same constraint on each will allow more water through than one large stream with the same small constraint on it.
What happens to the resistance in a parallel circuit when more light bulb is added?
Adding anything(yes,even a superconductor) to a any circuit adds resistance, especially devices that are by there very nature high resistors
When more light bulbs are added in parallel to a circuit what happens to the total resistance of the circuit?
"http://www.tpub.com/neets/book1/chapter3/1-26.htm" This site explains how to calculate the resistance, but it decreases the resistance when you add more.
What happens to amperage in series and parallel circuits?
In series, Amperage remains constant. In parallel, Amperages are added.
What happens to the voltages across the light bulbs in a parallel circuit change as more light bulbs are added to the circuit?
nothing
What happens to the total current provided by the battery as more bulbs are added to a parallel circuit?
The total current increases in this case.
What happens to the voltage if batteries if they are setup in a parallel and a series circuit?
Assuming all of the individual batteries are the same voltage, if arranged in a parallel circuit the voltage is the same as any one battery. If arranged in a series circuit the voltage will be the sum (the total) of all of the batteries added together.
If a new bulb is added and the electrical circuit becomes dimmer is it a parallel circuit?
No it's series circuit.
What happens to a parallel circuit if more bulbs are added?
Total power consumption increases with each bulb. The remaining bulbs continue to operate unchanged.
If you have a DC passing through a circuit will the current decrease when you add a DC motor and if so by how much?
In the circuit where the DC motor is added, it was not specified whether the motor was added in series or in parallel to circuit elements. If it was added in series, it will increase circuit resistance and it will cause circuit current to go down. In parallel, the motor will reduce total circuit resistance, and circuit current will increase.

What is parallel electricity?
i shocking sign of tunderAnswerThere is no such thing as 'parallel electricity'; you are probably thinking about 'parallel circuits'?A parallel circuit is one in which invidual loads are arranged in separate 'branches', with each branch subject to a common supply voltage. The individual branch currents may be added in order to determine the supply current.
Why does the total circuit resistance decreases when more devices are added to a parallel circuit?
Does it? See Related Links
What is a parralell curcuit?
• In a parallel circuit, there are junctions in the circuit so the current can flow around the circuit in more than one way. • In a series circuit the current decreases as more bulbs are added. •In a parallel circuit, as more bulbs are added, the current increases. • This is because bulbs added in parallel offer less resistance
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.
