What else can I help you with?
A conducting sheet of material has cross sectional area 10mm 20mm the material has a resistivity 1000 ohm calculate thickness of the materail required to give a resistance of 5 k ohm?
resistivity is not measured in ohms, it is measured in ohm-meters. Assume you mean 1000 ohm-meters. By "cross sectional area 10mm 20mm" I'll assume you mean a "cross section of 10mm by 20mm". You have already defined the thickness to be 10mm, so I can't calculate that, so I'll assume you want the length. That's 3 major corrections I had to make. I may well me making the wrong assumptions. You really need to write carefully. One of the most important traits in an engineer is the ability to write and speak carefully and correctly. anyway, here is my corrected version: A conducting sheet of material has cross sectional of 10mm x 20mm. The material has a resistivity of 1000 ohm-meter. Calculate the length of the materail required to give a resistance of 5 k ohm? the calculation is easy. 1000 ohm-meters / 5000 ohms = 0.2 m = 20 cm
The electrical conductivity of metals which is expressed in ohm-1 m-1 is of the order of?
In the range of 1 x 10^7 1/ohm-m . That's one times ten to the seventh power.
What is the formula for calculation of wire resistance?
R = resistance = rho * L / S rho is resisitivity in [Ohm m], it depends on the material (Copper: 2e-8 [Ohm m]) L is wire length [m] S is wire cross section [m] EDIT: for high frequencies, you may also wanto to take sink effect into account (~MHz)
What do MCM stand for in older electrical books?
MCM stands for 1000's circular mils. Broken down MCM means 1000's (M) of (C)ircular (M)ils. A Circular Mil means the area of a circle 1/1000 inch in diameter. 1000 MCM conductors are 1 inch in diameter.
How you convert Amps into MVA?
1mva = 1000kva so you simply divide by 1000. 10000KVA = 10MVA K = kilo = 1000 M = mega = 1000000
1000 cm equals how many m?
since100 cm = 1 m, 1000 cm = 10 m.
1000 cm is how many m?
1000 centimeters equals 10 meters. 1 cm = 1/100 m ⇒ 1000 cm = 1000 × (1/100) m = 10 m
10 m how many cm?
1000
How many meters in 1000 cm?
100 cm = 1 metre so 1000 cm = 10 m
How many centimetres are there in 10metres?
1 m = 100 cm 10 m = 1000 cm
How many centimeters are in 1000 meters?
1000 cm = 10 m How much is 1000 cm in metres? Well, 100 cm is 1 m. So, 9 more 100 cm is 1000 cm and makes it 10 m. I hope this helped you. -TaylorSwift.Fan
What is 1 cm multiplied by 1000 equal to?
1 cm multiplied by 1000 equals 1000 cm or 1 meter.
How many Cubic cm in a cubic m?
1000000cubic cm in a cubic m 1000 cubic mm in a cubic cm
How many mm in a cm or m?
10 in a cm, 1000 in a metre.
1000cm equals how many m?
1000 cm = 10m .
How many cm in 1000 m?
100,000 (1m = 100cm)
How many cm are in a km?
100,000. There are 100 cm in one m, and 1000 m one km, so 100 x 1000 = 100,000There are 100,000 cm in a km.
