Write the amplitude of 1/i

Question

Write the amplitude of \(\frac{1}{i}\)

Answer 1

. Given, \(\frac{1}{i}\)

Rationalise the denominator by multiply numerator and denominator by i

\(\frac{1\times i}{1\times i}\) = \(\frac{i}{i^2}\)= \(\frac{i}{-1}\)= -i = 0 - i

The real part in the complex number 0– i is 0 and imaginary part is – 1 

∴ The amplitude is given by
