Question
o make a blue LED and red LED glow, which requires more pressure to be applied to the piezoelectric generatorsa.Blue LED = Red LEDb.Blue LED > Red LEDc.Blue LED < Red LED
Solution
The pressure applied to piezoelectric generators doesn't determine the color of the LED that will glow. The color of an LED is determined by the material/semiconductor used in it, not by the amount of pressure or power applied. Therefore, the pressure needed to light up a blue LED and a red LED from a piezoelectric generator would be the same, assuming the LEDs are of the same power rating. So, the answer is a. Blue LED = Red LED.
