1potentiometr se measure kar lo
1)The barrier potential of a sillicon p-n junction is 0.7 V. Can we measure it using voltmeter.
2)Which one will you prefer for the rectification of low AC voltages - a Si diode or a Ge diode? Why?
3)Why a transistor cannot be used as a rectifier?

practicals khatam ho gaye aur mein school nahi jaata aajkal.
Aur koi answer hai?
132)Which one will you prefer for the rectification of low AC voltages - a Si diode or a Ge diode? Why?
Ge-diode should be used as it has lower knee voltage than Si-diode.So,there will be less wastage of energy.
3)Why a transistor cannot be used as a rectifier?
If a transistor is to be used as a rectifier then either of its Emitter-base or Collector-base part is to be used.But the base is very lightly doped in a transistor.Hence,it can't be used.
