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).
What else can I help you with?
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?
Well, honey, in a parallel circuit, you can't just add up the resistances like you're at a buffet. You gotta use the formula 1/Rtotal = 1/R1 + 1/R2 + 1/R3. Plug in the values and you'll find the total resistance is 6.67 ohms. So, grab your calculator and get to work, darling.
What is The ohm meter reads 40 ohms on the resistsnce x 10 range how much is resistance?
If the ohm meter reads 40 ohms on the resistance x 10 range, the actual resistance value is 40 ohms multiplied by 10. Therefore, the resistance is 400 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
1. A circuit for a remote to a model car racetrack has three resistors in series R1 20 ohms R2 12 ohms and R3 8 ohms. What is the equivalent resistance?
To find the equivalent resistance of resistors in series, you simply add their resistances together. In this case, the equivalent resistance ( R_{\text{eq}} ) is calculated as follows: [ R_{\text{eq}} = R_1 + R_2 + R_3 = 20 , \text{ohms} + 12 , \text{ohms} + 8 , \text{ohms} = 40 , \text{ohms}. ] Thus, the equivalent resistance of the circuit is 40 ohms.
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 circuit's total resistances?
In a parallel circuit, the total resistance is calculated as the reciprocal of the sum of the reciprocals of each individual resistance. So, for three resistances of 20 ohms, 20 ohms, and 10 ohms, the total resistance will be 1 / (1/20 + 1/20 + 1/10) = 1 / (0.05 + 0.05 + 0.1) = 1 / 0.2 = 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.
Perallel circuit two of them are rated 20 ohms one is 10 ohms what is the cicuits total resistance?
5 ohms
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.
There are three sources of resistence in a parallel circuit two of them are rated at 20 ohms the other 10 ohms what is the circuits total resistance?

How do you write 20 million ohms?
To write 20 million ohms, you can express it as 20,000,000 ohms. In scientific notation, it can be written as 2 x 10^7 ohms. Both formats effectively convey the same resistance value.
What is the total resistance of a series circuit with 5ohms10 ohms 20 ohms?
35 ohms
What is The ohm meter reads 40 ohms on the resistsnce x 10 range how much is resistance?
If the ohm meter reads 40 ohms on the resistance x 10 range, the actual resistance value is 40 ohms multiplied by 10. Therefore, the resistance is 400 ohms.
