Is there more resistance in the series circuit or the parallel circuit?

Ohm's Law says!
R=V/I
Resistance is directly proportional to Voltage. In series circuit, due to adding the resistance, total voltage will be increased, due to increasing of total voltage, total resistance of the series also be increased.

∙ 13y agoLet's assume you have three standard 60 Watt light bulbs wired in parallel in your hoime. There is 120 volts across each bulb. Each bulb draws 1/2 amp. Therefore the circuit as a whole draws 1.5 amps.
The same three bulbs connected in series with the same 120 volt supply draw about .167 amps.
Using Ohm's Law in each case we see in case one that the resistance across the parallel circuit is 80 ohms; and in the series circuit the resistance is 720 ohms.
Another way to see this is through the formulas for series and parallel resistances. For two resistances of R1 and R2 in parallel the results is
1/Reqv = (1/R1) + (1/R2) + (1/R3) + . . .
For series R eqv = R1 + R2 + R3 + ...
Ohm's Law Voltage = Current x Resistance

∙ 14y agoOne does not necessarily have more resistance than the other; it all depends on the voltage of the power source (battery) and the amount of Ohms in each resistor.

∙ 6y agoIf you connect the SAME resistors in parallel or in series, the series circuit will always have the greater equivalent resistance.
Wiki User
∙ 6y agoNo. If you connect two or more resistors in parallel, the equivalent resistance of the circuit will be LESS than that of any individual resistor.

How to calculate a parallel circuit with more than one load in its branches?
If a 'parallel' circuit has more than one load in its (not "it's"!) branches, then it is not a parallel circuit, but a series-parallel circuit! To resolve the circuit, you must first resolve the total resistance of the loads within each branch.
How to find Equivalent resistance when you have both parallel and series resistors?
To find equivalent resistance when you have both parallel and series resistors, start simple and expand... Find the smallest part of the circuit, such as a pair of resistors in series or a pair of resistors in parallel, and compute the equivalent single resistor value. Repeat that process, effectively covering more and more of the circuit, until you arrive at a single resistance that is equivalent to the circuit. For resistors in series: RTOTAL = R1 + R2 For resistors in parallel: RTOTAL = R1R2/(R1+R2)
What is the difference between a series circuit and as parallel circuit?
series circuit can only move on one patha parallel circuit has two more paths for the electric carve to follow
How are series circuit and parallel circuits?
For parallel circuit, there's bronchus which mean the electric current'd have to choose which path to go. There's a main loop and more than one bronchus.If the bulb in one of the bronchus break down,the other bulbs would still light up. For series circuit,there's only one path for the electric current to flow through.If one of the bulb breaks down,the other'd go out as well. The electric current of evbery bulb in a series circuit is the same while the electric current of bulb in parallel circuit are not the same. The sum of the bronchus in a parallel circuit is equal to the main loop's.The more bulbs in a path,the more resistance will there be and less brighter it will be.A larger current will flow through the path with lower resistance so te brightness of the bulb of the bronchus will hace differences asc well.

Light bulb in parallel circuit brightness?
Two bulbs connected in parallel are brighter than two connected in series. The resistance of the circuit is lower, electrons can flow more easily.
What type of circuit has more than one circuit on a wire a series circuit or a parallel circuit?
A parallel circuit is :)
Does more current flow through a parallel circuit than a series circuit?
Two resistors in parallel are equivalent to a single component with a lower resistance than either of the pair. Two resistors in series are equivalent to a single component with a resistance equal to the sum of the pair, therefore a higher resistance. For a given potential difference, more current in total will flow through two resistors in parallel than through the same resistors in series.
Which uses more energy parallel circuit or a series circuit?
That depends. For example, if the circuit is consisted of two resistors, 2 ohms each, the equivalent resistance (Req) of these two resistors in series is 4 ohms, and the Req of these two resistors in parallel is 1 ohm. If the same voltage is applied, say 4 V.power consumed in a resistance = V2/R.The parallel circuit: Power = 4 * 4 / 1 = 16 [W].The series circuit: Power = 4 * 4 / 4 = 4 [W].With everything else the same, a parallel circuit consumes more energy than a series circuit.Note that circuits of only simple resistors are discussed. You need to consider each circuit on its merit.================================AnswerIt depends. In both cases, the total energy expended will be the sum of the energies expended by each individual load.
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.
Is a ammeter connected in series or in parallel with the circuit under test?
An ammeter is connected in series. A voltmeter is connected in parallel. ammeter should always be connected in series instead of parallel becoz it is a low resistance device and we know that resistance is inversly proportional to current so more current will pass through it and if it is connected in parallel than it may get damaged
How many paths does a parallel circuit have?
a parallel circuit has 2 or more paths.a series circuit has 1 path.a parallel circuit is better for homes and school

Which is more wired the parallel or series circuit?

What is the difference between series and parallel circut?
If two or more circuit elements are connected in series, the current must pass through each of them in turn. If two or more circuit elements are connected in parallel, that means there is a "fork in the road". In this case, part of the current will pass through one element, and part, through another one.
