Is glass or metal a better conductor?
Glass has a higher conductivity than thin plastic but,it is still lower than metal so metal may be a better conductor
What is the total voltage for R1 20 ohms R2 30 ohms and R3 18 ohms?
As you have not supplied any information, other than the resistance of the individual resistors, there is no way in which your question can be answered.
What is the total resistance of a 6-ohm resistor and a 12-ohm resistor in a parallel series?
In series like so ---6 ohms ---- 12 ohms --- , the total resistance is just 6 ohms + 12 ohms.assuming you mean in parallel like this:_|---6 ohms-----|-|~|-_|---12 ohms---|then the resistance of this can be calculated like so:1/6 ohms + 1/12 ohms = 1/R (where R is the resistance of the circuit as a whole)2/12 ohms + 1/12 ohms = 1/R3/12 ohms = 1/R1/4 ohms = 1/Rso R = 4 ohmsA few notes, if the resistors are in parallel the total resistance will always be less than or equal to the lowest resistance in parallel (i.e 6 ohms in parallel with 12 ohms will have resistance less than 6 ohms).Also if two resistances in parallel are the same, then the resistance is half of the resistance of both resistors (i.e. 1/2 ohms + 1/2 ohms = 1/R; 1 = 1/R, R=1 ohm which is half of 2 ohms).This process can be extended to 2 or more resistors in parallel.i.e if we had a 6 ohm, 6 ohm and 12 ohm resistor in parallel we could go1/6 ohms + 1/6 ohms + 1/12 ohms = 1/R(1/6 ohms + 1/6 ohms) + 1/12 ohms = 1/R1/3 ohms + 1/12 ohms = 1/R4/12ohms + 1/12 ohms = 1/R5/12 ohms = 1/Rso R = 12/5 ohms or 2.4 ohms
Why is air a better insulator than solids?
.air you can breath and if there was no air there would be no things that live out of sea
What is the difference between 6 ohms and 8 ohms?
Though it is tempting to say the difference is 2 ohms (8 ohms minus 2 ohms equals 6 ohms), lets look at some things. The 6 ohms is 3/4ths the resistance of the 8 ohms. If the resistances are loads, the 6 ohm load will draw 1/3rd more current than the 8 ohm load. The 8 ohm load will draw 3/4ths as much as the 6 ohm load. Those are some differences between 6 ohms and 8 ohms.
Is mega ohms more them k ohms?
Yes, one mega ohm is more than one kilo ohm. Mega means million, kilo means thousand.
Is fibreglass a better insulator than vacuum?
No. If you can get it, vacuum is the best insulator.
Is glass a better insulator than styrofoam?
no
Which is the best insulator thermocol or air or cotton or aluminium?
Air is better than thermocol as insulator. .....
Is styrofoam a better insulator than wood?
Yes
Is cardboard a better insulator than styrofoam?
No, it's not
Is a material with a lower R-value a better insulator than a material with a high R-value?
No. A higher R-value is a better insulator.
Air is a better insulator than fiberglass batting?
Fiberglass insulation is better than air, but closed cell foam is better.
How can you determine if foam is a better insulator than paper?
yes you can test it under a lamp and see the temp. for the foam and paper and if one has the lowest than that's the better insulator!good luck!
Is plastic a better insulator than metal?
No, it is not. Metals conduct heat much better than most plastics. However, if the metal is used as a reflector of radiated heat, it will insulate better than plastic would.
Why does the glass on a window pane feel cooler to the touch than the wood frame surrounding the glass?
Wood is a better thermal insulator than glass, which is easily cooled.
Is air or fiberglass a better insulator?
i hope air is better than fibre glass
