Is resistance in a series circuit equal to the largest resistor in the series?
No. The resistance in a series circuit is all the resistor values added together. eg. If two resistors were in a circuit, one was 10 ohms and the other was 30 ohms, the resistance in the circuit would be 30 ohms. Hope this helps!
What happens to the current when more resistors are added in series?
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.
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.
When an ammeter is connected to measure current circuit current will decrease sightly because R total decreases after the meter is inserted?
Current will be decreased because of the resistance of the ammeter added to the circuit's resistance. In other words total resistance increases.
What would happen to a series circuit if another bulb was added?
A: Adding any resistance bulbs or whatever in a series circuit will reduce current and will reduce total power. In this case the bulb will glow dimmer as any additional bulbs are placed in the series circuit. this is true if the same input source is kept constant.
In a series circuit each device that is added to the circuit decreases the?
Ohm's Law answers your question. Voltage = Current x Resistance. In a series circuit you are in effect adding resistance. If the Voltage remains constant then the answer is obvious looking at the equation above.
In a series circuit each device that is added to circuit decreases the?

What would happen if another bulb was added to another series circuit?
In a series circuit, if another bulb is added, it is going to dim.
Why does the total circuit resistance decreases when more devices are added to a parallel circuit?
Does it? See Related Links
When you add resistors that are in a series to a ciruit?
You raise the total resistance by that amount if added in series to a circuit. If you add them in parallel to a circuit then that total resistance will be less than the total of the added circuit.
If a new bulb is added and the electrical circuit becomes dimmer is it a parallel circuit?
No it's series circuit.
How does the brightness of each bulb in a parallel circuit compare to the brightness of the bulb in a series circuit?
In a parallel circuit, each bulb receives the full voltage of the power source, so all bulbs shine at their full brightness. In a series circuit, the brightness of each bulb decreases as more bulbs are added because the voltage is shared among all bulbs.
How is resistance added in a series circuit?
Resistance in a series circuit is added by simply connecting resistors end-to-end. This results in the total resistance being the sum of the individual resistances. The current passing through each resistor in a series circuit remains the same.
What is downstream in electrical?
The terminology down stream refers to an electrical circuit and where devices are connected into the circuit. In reference to the breaker that feeds the circuit everything is down stream from it. If a GFCI receptacle is added into the circuit as the first device, the GFCI can be wired to allow all of the regular receptacles to be protected down stream from that GFCI. Every device added to the circuit will be down stream from the one that is ahead of it. The only device that will not have something down stream from it will be the last device in the circuit.
When additional stops are added to a control circuit should they be connected in series or parallel?
series
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.
