Question
o make a red LED glow, what was the approximate voltage produced in the piezoelectric generatora.0.5 Vb.2.5 Vc.1.2 V
Solution
The question seems incomplete. However, typically, a red LED requires a voltage of approximately 1.8 - 2.2 V to glow. So, the closest answer would be 2.5 V. But please check the specific requirements of your LED and the context of the question.
