Using dimensional analysis the resistivity in terms of fundamental constants `h, m_(e), c, e, epsilon_(0)` can be expressed as

Dimension of resistance R in terms of mu0 & epsilon_(0) are

Using dimensional analysis obtain an expression for the speed of transverse waves in a stretched string.

Write the expression for speed of light in terms of mu_(0) and epsilon_(0) , explain the terms used.

Dimension of resistance R in terms of mu_0 & epsilon_(0) are

Dimension of resistance R in terms of mu_0 & epsilon_(0) are

Statement-I: Dimensional analysis can give us the numerical value of proportionality constants that may appear in an algebraic expression. Statement-II: Dimensional analysis make use of the fact that dimensions can be treated as algebraic quantities.

If electronic charge e, electron mass m, speed of light in vacuum c and Planck's constant h are taken as fundamental quantities, the permeability of vacuum mu_(0) can be expressed in units of :

If electric charge e, electron's mass m, speed of light in vaccum c and Planck's constant h are taken as fundamental quantities, the permeability of vaccum mu_(0) can be expressed in units of :
