Answer the following questions related to reactance without performing any numerical calculation.
(i) Using their defining expressions, explain how inductive reactance and capacitive reactance each depend on the frequency of the applied alternating emf.
(ii) What happens to the magnitude of inductive reactance and capacitive reactance, respectively, as the frequency approaches zero? Give a physical interpretation.
(iii) Describe the behaviour of these reactances as frequency becomes very large, and comment on the consequent phase relation between voltage and current in each case.
