Well, the total circuit resistance depends on the type of connection.
If the two resistances (or any number of resistances) are connected in series, IE. one resistance end is connected to one end of another resistance, the the circuit total resistance is the sum of the two resistances. say two resistances r1 and r2 are connected in series the total resistance is r1+r2 (in this case its 30 ohms).
If the resistances are connected in parallel IE. both the ends of a resistance are connected to both ends of another resistance then the total resistance in this case shall be (r1*r2)/(r1+r2) ,( that is 6.67 ohms in given case).

There are three sources of resistance in a parallel circuit Two of them are rated at 20 ohms the other at 10 ohms What is the circuit's total resistance?
-- If the 20 ohms and the nother 10 ohms are configured in series, then the totalnet effective resistance is 30 ohms.-- If they are configured in parallel, then the total effective resistance is 62/3 ohms.
At 120 vac what is the amp draw of total resistance series circuit with 5 ohms 10 ohms 20 ohms?
The net effective resistance of 5 ohms, 10 ohms, and 20 ohms in series is 35 ohms.The current through the net effective resistance is [ I = E/R ] = 120/35 = 3.429 Amp. (rounded)Note: If you try this at home, be aware that these resistors will dissipatethe 5 ohm . . . 58.8 wattsthe 10 ohm . . . 117.6 wattsthe 20 ohm . . . 235 watts .These are no ordinary resistors, such as hang on the wall in plastic bags at Radio Shack.These would have to be 'power' resistors ... like heating coils in a toaster or hair-dryer.
What would the resistance of the wire if the resistance is 10 ohms be the same if it were twice as long?
The resistance of a conductor is directly proportional to its length, hence increasing the length twice will increase the resistance twice as well. Therefore the resistance will be 2*10 = 20 Ohms
A 3 ohm 2 ohm and a 5 ohm resistor are in series What is the total resistance in ohms of the system?
10 Ohms.
Is ohms bigger unit to megohms?
An ohm is a unit of electrical resistance. A kilohm is 1,000 ohms resistance, while a megohm is 1,000,000 ohms resistance.
There are three souces of resistance in a parallel circuit Two of them are rated at 20 ohm the other at 10 ohms What is the circuit's total resistance?
Three resistors in parallel: 20 ohms, 20 ohms, 10 ohms.1/ total resistance = (1/10) + (1/20) + (1/20) = (2/20) + (1/20) + (1/20) = 4/20 = 1/5 mho.Total resistance = 5 ohms
There are three sources of resistance in a parallel circuit. two of them are rated at 20 ohms the other at 10 ohms. what is the circuits total resistance?
5 ohms
How many Ohm resistances do you need to connect in parallel to produce a total resistance of 10 Ohm?
For an end-result of 10 ohms, you can have 1 resistance of 10 ohms, or 2 parallel resistance of 20 ohms each, or 3 resistances of 30 ohms each, etc.

What is the total resistance of 20 ohms?
Could it be.... 20 ohms(?)
Three soures of resistance in a parallel circuit two of them are rated at 20 ohms the other at 10 ohms what is the circuit total resistance?
The question appears to be describing three resistors all in parallel.The reciprocal of their net effective resistance is(1/20) + (1/20) + (1/10) = (2/20) + (1/10) = (1/10) + (1/10) = (2/10) = 1/5.The net effective resistance is [ 1 / (1/5) ] = 5 ohms.

What is the total resistance of a series circuit with 5ohms10 ohms 20 ohms?
35 ohms
How do you converts ohms to dB?
You must find a resistance value for 0 dB as reference. If 1 Ohm = 0 dB then 10 ohms = 20 dB and 100 ohms = 40 dB.
What is the total resistance is V is 10 volts R1 is 1000 ohms and R2 is 1000 Ohms?
If they're connected in series the total resistance is 2000 ohms. If they're connected in parallel the resistance is 500 ohms.
