Question

The maxima and minima voltage of the standing wave are 6 and 2 respectively. The standing wave ratio is (a) 2 (b) 3 (c) 1/2 (d) 4 This question was posed to me by my school principal while I was bunking the class.

Answer 1

Correct choice is (b) 3 Easy explanation: The ratio of voltage maxima to voltage minima is given by the standing wave ratio SWR. Thus S = VMAX/VMIN. On substituting the given data, we get S = 6/2 = 3.
