The 6 V Zener diode shown in the figure has negligible resistance and a knee current of 5 mA. The minimum value of R (in `Omega`) so that the voltage across it does not fall below 6 V is

The silicon diode shown in fig. is rated for a maximum current of 10mA . Calculate the minimum value of resistor R . Asume the forward voltage drop across the diode to be 0.7V .

A 10V of zener diode is connected in series to a resistance across a power supply of 50 V calculate the minimum value of resistance required such that the zener current is 25 mA

The junction diode in the following circuit requires a minimum current of 1 mA to be above the knee point (0.7 V) of its I-V characterstic curve. The voltage across the diode is independent of current above the knee point. If V_(B)=5 V , then the maximum value of R so that the voltage is above the knee point, will be

The junction diode in the following circuit requires a minimum current of 1 mA to be above the knee point (0.7 V) of its I-V characterstic curve. The voltage across the diode is independent of current above the knee point. If V_(B)=5 V , then the maximum value of R so that the voltage is above the knee point, will be

In the current versus voltage characteristics of a diode minimum current of 1 mA is required for the knee voltage to be is connected in a cirucit the minimum value of R so that the voltage is above knee point is
