If the input ac is 10 Vrms, the maximum voltage that will appear across the diode of a half-wave rectifier with a capacitor input filter will be

Given for an FET, gm = 9.5 mA/volt, total capacitance = 500 pF. For a voltage gain of-30, the bandwidth will

The parameters of an, FET are gm = 3mA/V, rd = 312 R1 = 3k as a source follower load. The input impedance is give by

In a FET

In an FET as V changed from zero to increasing reverse bias, the value of gm

A JFET is set up as source follower. Given, p. = 200, rd = 100 k and source load resistance RL = 1k. The output resistance Re is given approximated by

A 24 V, 600 mW, Zener diode is to be used for providing a 24 V stabilized supply to a variable load. Assume that for proper Zener action, a minimum of 10 mA must flow through the Zener. If the input voltage is 32 V, what would be the value of R and the maximum load current?

The breakdown voltage of a transistor with its base open is BVcE0 and that with emitter open is BV"0, then

As compared to a full wave rectifier using two diodes, the four diode bridge rectifier has the dominant advantage of
