∙ 12y agoWhen the resistors are in series then the equivalent resistance is got by the sum of the resistance values. Hence the equivalent resistance is 8+8 = 16 ohms.

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.
When a 30.0-V emf device is placed across two resistors in series a current of 14.0 A is flowing in each of the resistors. When the same emf device is placed across the same two resistors in parallel?
There is insufficient information in the question to answer it. 30 volts generating 14 amperes means the two resistors have a total series resistance of 2.143 ohms. Since no relationship was stated, we don't know the value of the individual resistors. If the two resistors had the same resistance, the net parallel resistance would be 0.536 ohms, and a current of 56 amperes would flow.
What happens to the current through a series circuit as more resistors are added in series?
If the bulbs are in a series circuit the voltage drops at each bulb drops as additional bulbs are added. In a parallel circuit the voltage is constant no matter how many bulbs are added.
Math Problems with solutions about series and parallel circuit?
I have two resistors, a 2-ohm and a 3-ohm.What is their combined effective resistance when they are connected in series ?Answer: R1 + R2 = 5 ohmsWhat is it when they are connected in parallel ?Answer: 1 / [ (1/R1) + (1/R2) ] = 1.2 ohms
What is the ratio of equivalent resistance of series and parallel combination of n equal resistance to the equivalent resistance on parallel combination?
1
What is the relations for the equivalent resistance of a number of resistors connected in series?
Resistance in series is simply the sum of the resistors. RSERIES = SummationI=1,N(RI)
To connect a pair of resistors so that their equivalent resistance is greater than the resistance of either one should you connect them in series or in parallel?
When many resistances are connected in series, the equivalent resistance is greater than the greatest single resistance. When many resistances are connected in parallel, the equivalent resistance is less than the smallest single resistance.
What is the rule for finding the total resistance of a number of resistors connected in series?
If the resistors are in series, then the total resistance is simply the sum of the resistances of each resistor.
Do 5 1 ohm resistors equal 1 5 ohm resistor?
it depends on how we are connecting them.if 5 1 ohm resistors are connected in series then the equivalent resistance is 5 ohms.if they are connected in parallel then the equi resistance is 1/5 ohms.
What is the total resistance in a circuit that contains three 60 resistors connected in series?
The total effective resistance of resistors in series is the sum of the individual resistances.Three 60-ohm resistors in series have a total effective resistance of (60 + 60 + 60) = 180 ohms.
What is the combined resistance of a 39k and a 47k resistor connected in series?
86k. Resistance in series is the sum of the individual resistors.
How can you connect resistors to produce an equivalent resistance which is the same as the resistance of each individual resistor?
You can connect 4 resistors in series-parallel, i.e. two in series, both in parallel with another two, and the effective resistance would be the same as one resistor. Similarly, you can connect nine resistors in 3x3 series-parallel, or 16 resistors in 4x4 series-parallel, etc. to get the same resistance of one resistor.
What is the net resistance of two resistor connected in series?
The net resistance of two resistors connected in series is the sum of the two resistances. RSERIES = Summation1toN RN
What is the resistance in a circuit if two 60ohm's resistors are connected in series?
The equivalent resistance of multiple resistors connected in series is the sum of theindividual resistances.(10 + 60 + 50) = 120 ohms for this particular trio of resistors in series.It makes no difference what battery they may be connected to, or if they're connected toany power supply at all.
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.
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 happends to resistance when resistors are wired in series?
The resistance of two or more resistors connected in series is the sum of the individual resistances. (If any of the connections between them is sloppy and involves some resistance at the connection, then that also has to be added in.)
