Illustrate VI Characteristics of PN junction diode (10)
Illustrate Half Wave Rectifier. Disadvantage of Half Wave Rectifier. Determine ripple factor of Half Wave Rectifier.
Q. These data were obtained from tests carried out on a 10-kVA, 2300:230-V, 60-Hz distribution transformer: • Open-circuit test, with low-voltage winding excited: applied voltag
Q. The energy stored in a 2-µF capacitor is given by w c (t) = 9e -2t µJ for t ≥ 0. Find the capacitor voltage and current at t = 1s.
Mode1 When the positive pulse from PWM is applied to the transistor Q shown in figure it gets turned on. In this condition current flows through transistor Q and.
In real life, transformers have losses which cause their behaviour to deviate from the ideal. Explain the reasons for this non-ideal behaviour
dis advantage of series clippers?
Q. What is power gain? Power gain is the ratio of power delivered to the load to power delivered to the amplifier is the power gain. A p =P o /P i =V o I o /V i I s
A Zener diode has the specifications VZ=6.8V and PDmax.=500mW. Assume RZ=0. (a) Find the maximum allowable current iZ when the Zener diode is acting as a regulator. (b) If a sing
Q. What do you mean by Amplifier block? An amplifier can be modeled as a two-port device, that is, a box with two pairs of terminals designated as input and output, as shown in
1. A 230/1000V 50 Hz, single phase transformer has the following test data: Open circuit test (L.V.) Primary voltage = 230V Primary current = 1.30 A Input power
Q. Balanced wye-connected loads drawing 10 kW at 0.8 power factor lagging and 15 kW at 0.9 power factor leading are connected in parallel and supplied by a 60-Hz, 300-V, three-phas
