what is the capacitance of a 1m long hifi cable where the central conductor is 1mm in diameter and the shield is 5mm in diameter ?

A wire 50 cm long and 0.12mm diameter has a resistance of 4.0 Omega find the resistance of another wire of the same material whose length is 1.5m and diameter is 0.15 mm

Wolffia a small plant about 1 mm in diameter is a:

Two conductors are made of the same material and have the same length. Conductor A is a solid wire of diameter 1 mm. Conductor B is a hollow tube of outer diameter 2 mm and inner diameter 1mm. Find the ratio of resistance R_(A) to R_(B) .

Two conductors arc made of the same material and have the same length. Conductor A is a solid wire of diameter 1 mm. Conductor B is a holJow tube of outer diameter 2 mm and inner diameter lrrun. Find the ratio of resistance R_(A)" to " R_(B) .

A metallic wire of length 3 m is stretched to produce an elongation of 2 mm. IF the diameter of the wire is 1mm, then find the decrease in its diameter due to this elongation.Poisson's ratio for the material of the wire is 0.24.

The cross section of a cable is shown in fig. The inner conductor has a radius of 10 mm and the dielectric has a thickness of 5 mm . The cable is 8 km . Long. Then the capacitance of the cable is [log_(e) 1.5 =0.4] . .
