(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. Given the K map of a logic function as shown in Figure, in which ds denote don't-care conditions, obtain the SOP expression.
Q. Briefly explain about Transients in circuits? The total response of a system to an excitation that is suddenly applied or changed consists of the sum of the steady-state and
