Homework Statement
Two charged conducting spheres of radii a and b are connected to
each other by a wire. What is the ratio of electric fields at the surfaces
of the two spheres? Use the result obtained to explain why charge
density on the sharp and pointed ends of a conductor is higher
than on...
we write \frac{1}{R}=\frac{1}{R_1}+\frac{1}{R_2} where R is the equivalent resistance of R_1 and R_2.
Let there is an error in the measurements of R_1 and R_2 of \pm \Delta R_1 and
\pm \Delta R_2 respectively.
Is it correct that
\frac{\Delta R}{R^2}=\frac{\Delta...
The ampere is that constant current which , if maintained in two straight parallel
conductors of infinite length, of negligible
circular cross-section, and placed 1 metre apart in vacuum, would produce between
these conductors a force equal to 2 × 10 ^{–7} Newton per...
