Quizplus · Accepted Answer

An open C3 (coupling capacitor between the collector of Q1 and the next stage) would result in a higher output signal at the collector of Q1 because it would remove the AC path to the next stage, potentially causing the DC level at the collector to appear higher than normal. This is because the coupling capacitor's role is to pass the AC signal while blocking DC, and if it's open, the AC signal cannot be properly transferred.
