The knee voltage, for Ge and Si diode, are (respectively)
Zener diode, having a Zener voltage , is said to be in ‘ OFF ’ state when reverse voltage is such that
A Zener diode is generally used as,
A characteristic feature of IV graph of a Zener diode is
In a CE transistor (in active mode), the emitter-base junction has a resistance (r) while the collector-base junction has a resistance R. We can say that r and R, are, respectively, a
The input characteristics curves of a transistor, are curves between
Two multimeters (A and B) require a total markings of 20 mA and 60 mA, respectively, to give full-scale deflection. It implies that,
The (small) amplitude, of the oscillating bob, of a simple pendulum, becomes 75% of its initial value in a time of T seconds. The percentage loss in energy, of the bob, in this time, is nearly
