a) A 230 V/25V, 50 HZ transformer with a rated primary current of 1,2 Amps is used to supply a number of 25 V, 30 Watt halogen light bulbs.
Assuming an ideal transformer and that it operates within its rated values, determine the maximum number of bulbs that can be used.b) A transformer is used to match impedances of 10 KΩ and 600Ω. Determine the turns-ratio for the transformer.
c) Questions (1) and (2) refer to an ideal or perfect transformer. In real life, transformers have losses which cause their behaviour to deviate from the ideal.
Consider the reasons for this non-ideal behaviour with reference to the above questions.
Explain the differences that you would expect if the load (lamps) in question 3a had consisted of reactive loads.
Explain Eddy currents. Eddy currents: Magnetic materials placed as in alternating magnetic fields have eddy currents also induced in them. It is because the material is subject

When three resistors R1, R2 and R3 are connected in parallel as shown in the diagram. For these resistors the equivalent resistance is given by: a. Derive a rule to
Property of material which allows it to be drawn out into wires is (A) Ductility. (B) Solder ability. (C) Super conductivity.

Uses of FET IGBTs (Insulated-gate bipolar transistor) see application in switching internal combustion engine ignition coils, in which fast switching and voltage blocking cap
Q. What is inter digit time? Break time is nominally 61 ms and make time is nominally 39ms. Digits are separated by idle period of 300 ms known as inter digit time. It is vital
Q. Open-loop control system? An open-loop system is one in which the control action is independent of the output or desired result, whereas a closed-loop (feedback) system is o
in case of a differentiator will the amplitude rise or falls?
