Piezo Transducer
Posted September 30, 2009

Help in few electronics questions.....?
Please give explanations also for the following questions:
1. For a low power load, which would you choose- a line regulated or a line regulated circuit.
2. What are the characteristics of a good filter circuit in a power supply?
3. What would happen to a regulator circuit, if a Zener diode is connected in the forward biased configuration? I think it will behave like a normal diode.
4. Why is the UJT used for designing relaxation oscillator?
5. If you were to design an instrument to measure pressure, would you prefer a piezo-electric crystal as a transducer?
Please write explanations also.
1. For a low power load, which would you choose- a line regulated or a line regulated circuit.
huh? line regulated or line regulated... what is the difference?
2. What are the characteristics of a good filter circuit in a power supply?
that it filter out the AC
3. What would happen to a regulator circuit, if a Zener diode is connected in the forward biased configuration? I think it will behave like a normal diode.
correct
4. Why is the UJT used for designing relaxation oscillator?
not used anymore, the 555 IC is cheaper and easier to design with.
5. If you were to design an instrument to measure pressure, would you prefer a piezo-electric crystal as a transducer?
yes.
