(a) For the Zener diode series voltage regulator shown in the Figure. calculate VL, IZ, VR and PZ for RL= 1.2 KΩ and repeat it for RL= 3 KΩ ?
Consider Zener breakdown voltage = 10 V and PZM = 30 mW
(b) Calculate Q point ( IC, VCE) for the network shown? Assume β = 75
Q. Show Advantages of Oscillators? Although oscillations can be produced by mechanical devices (e.g. alternators), but electronic oscillators have the following advantages:
Consider the circuit of Figure and obtain the complete solution for the voltage v C (t) across the 5-F capacitor and the voltage vx(t) across the 5- resistor.
Checking at Site - Testing of Meter The routine testing of meters should be carried out once in 3 years. Further, surprise checks should be conducted at the consumer's install
Q . Differentiate between an integrator and differentiator? Integrators 1 Integrators are circuits in which output voltage is proportional to the integral of the input.
Q. A silicon BJT has an emitter current of 5m Aat 300 K when the BEJ is forward-biased by vBE = 0.7 V. Find the reverse saturation current of the BEJ. Neglecting ICBO, calculate iC
which type of ic package is more advantageous,suitable and versatile
12. A capacitor is to be constructed so that its capacitance is 0.2µF and to take a p.d. of 1.25kV across its terminals. The dielectric is to be mica which, after allowing a safety
Q. What is the need of MODEM in data communication? Need of Modem: Modems are used to interface computers, computer networks in addition to other terminal equipment to teleco
