Describe how the current amplitude varies as the angular frequency of the source is slowly reduced from 1000 to 500 .

a-Amplitude is always constant.

b-Amplitude decreases.

c-Amplitude increases.

d-First amplitude increases next it decreases.

e-First amplitude decreases next it increases.

a - Amplitude is always constant.

Explanation:
