Alternating Current and Voltage - Technical MCQs

Q1:

Which point is the trailing edge of the repetitive pulse waveform in the given circuit?

A Point A

B Point B

C Point C

D Point D

ANS:A - Point A

Trailing edge is the opposite of a leading edge.

Here the waveform goes from 0 to 5 it is leading edge (i.e front edge).
Same falls from 5 to 0 is trailing edge (i.e back edge).

Here pointA is located at trailing edge.
