Three 8.0-W resistors are connected in parallel. What is their equivalent resistance?
It depends on their individual resistances, which you do not specify!
When 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.
In series the resistance is 16 Ohms; in parallel the resistance is 4 Ohms.
The sum of the individual resistances.
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.
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.
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.
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
Adding more resistors in parallel increases the number of possible pathways for current to flow, which effectively reduces the overall resistance that the current encounters. This is because the total resistance in a parallel circuit is inversely proportional to the number of resistors connected in parallel.
Resistance in series is simply the sum of the resistors. RSERIES = SummationI=1,N(RI)
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.
If the resistors are in series, then the total resistance is simply the sum of the resistances of each 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.
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.
86k. Resistance in series is the sum of the individual resistors.
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.
The net resistance of two resistors connected in series is the sum of the two resistances. RSERIES = Summation1toN RN
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.
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.
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)
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.)
