V=IR where V is voltage, I is current and R is resistance. You want to know what the current will be in a series circuit based on the resistance.
You need to know the voltage as well as the resistance, gives you the equation as follows
I=V/R
So if you have 10 volts and a 1 ohm resistor, the current will be 10 amps. If you increase the resistor to 10 ohms, your current will then be 1 amp.
In a parallel circuit, the resistance is equal to the sum of the inverse. For example. If I have two resistors of 2 ohms each in parallel, the equation would be
1/2 + 1/2 = 0.5 + 0.5 = 1
In that particular instance, your current would increase.

∙ 10y agoyes, The current flowing in a series circuit is given by the applied voltage divided by it's total resistance offered by the circuit.
hence if resistance of the circuit is changed, then total circuit resistance will change, so current will change.

How does a broken wire affect a series circuit?
because the circuit is not a full circuit so it wont work!
For bulbs connected in series the high watt bulb has high resistance?
No, the highest wattage bulb will have the lowest resistance.
Why circuit breaker are connected in series with load?
Because it needs to be able to cut the power to the load. That's why circuit breakers are always the first piece of equipment in a circuit after the power supply.
When 2 resistors are connected in parallel r1r2 are?
Two resistors connected in parallel are 1/2 the sum of their resistance. The resistance of two resistors connected in series is the sum of their resistance. For example: The total resistance of a 100 ohm resistor connected to a 200 ohm resistor in parallel is 100+200 divided by 2 = 150 ohms. The total resistance of a 100 ohm resistor connected to a 200 ohm resistor in series 100+200= 300 ohms.
Device used to determine the presence of an electrical charge is called?
There are, to my knowledge, two devices which can be used to measure electrical charge (I know your question asked for a device which determined the presence of an electrical charge but this achieves the same thing). These are the Ammeter and the voltmeter.1). Measuring electrical charge with an ammeterIn order to determine the electrical charge with an ammeter, you attach the device to an electrical circuit IN SERIES (this is important and will be explained at the end of this answer). This will then give you a reading of the number of amps, or coulombs per second. You can then use basic mathematics to determine the charge here as I will now demonstrate,Because we know that I = Q÷t (where I is the current in amps or the equivalent unit coulombs per second, Q is the charge in coulombs and t is the time in seconds), we are able to re-arrange this to calculate the value of Q,I = Q÷t=I×t = Q÷t×t=I×t = Qt÷t (note that the t variable will cancel out on the right hand side of the equals sign because t÷t = 1 and Q×1 = Q)=I×t = QTherefore the general formula to calculate the charge is,Q = I×tHowever in this particular problem, we can assume t = 1 because I is measured in amps or (more significantly) coulombs per second, i.e. C/t. Note that this formula can also be used to calculate the total electrical charge used in t seconds (where t doesn't equal 1)2). Measuring electrical charge with a voltmeterIt is possible to calculate the electrical charge of a circuit with knowledge of the voltage to a circuit; however it is important to note the following,-1. The total resistance of a series circuit = R1 +R2 + Rn-2. The total resistance of a parallel circuit = (1/R1 + 1/R2 + 1/Rn)-1-3. Because some circuits contain both parallel and series components, you may need to apply the above two formulas to different parts of the same circuit and then add those numbers together to arrive at the total resistance of a circuit with both series and parallel components.-4. There is a constant current for each and every component of a series circuit.-5. There is a variable voltage for each and every component of a series circuit.-6. There is a constant voltage for each and every component of a parallel circuit.-7. There is a variable current for each and every component of a parallel circuit.Armed with this knowledge, you can then calculate the charge in the circuit by first calculating the total amount of resistance in the circuit. We then need to input this number into ohms law (which is V = I×R) and then solving for I (which will be the total current),V=I×R=V÷R = I×R÷R=V÷R = I×1=I = V÷ROnce we have the total current used in the circuit, it is then possible to calculate the total charge by the formula Q =I×t (as explained in part one).There probably are other devices which can be used; however I am not aware of them.
What is the effect of the increasing the number of resistor in series?
A: In a series circuit the currant is the same for all components but the IR drop will change foe each. By adding Resistance the current will decrease accordingly
Does current change in a circuit having bulb in series with a resistance?
Absolutely the more Resistance is put in series the less current Will flow.
How is the total resistance in a series circuit is determined?
The total resistance in a series circuit is determined by adding (summing) the individual resistances of each component in the circuit.
What happens in a series circuit if the resistance is halved?
If you add a second resistor, the resistance of series circuit will increase.
How do you calculate the joint resistance in a series circuit with three resistances?
The resistance of a series circuit is simply the sum of the individual resistors.
How are resistance combined in a series circuit?
Resistances are additive in a series circuit.
Does current effect the resistance in an electric series circuit?
The resistance remains constant. The voltage would change, in accordance with Ohms' law, with a change in current.
Where is the most resistance lost in a series circuit?
Resistance isn't lost. The largest voltage drop will occur across the largest resistance in a series circuit.
In a series circuit when adding light bulbs does the current change?
Yes. The current is inversely proportional to the resistance. I = V / R where I is current, V is voltage, and R is resistance. Adding light bulbs adds resistance. Current is constant throughout a series circuit; it doesn't change no matter what. Voltage changes.
What is a resistance circuit?
It does not contain unidirectional outputAnswerA purely resistive circuit is an 'ideal' circuit that contains resistance, but not inductance or capacitance.
How can you make the resistance higher in a circuit?
A: practically any series resistance will do that
In a series circuit is resistance constant?
current
