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.
Compare with memory The contents of the memory of the memory location pointed by HL register pair are compared with the contents of the accumulator. The instruction f

Q. A transformer is rated 10 kVA, 220:110 V (rms). Consider it an ideal transformer. (a) Compute the turns ratio and the winding current ratings. (b) If a 2-load resistance
Q. A two-pole rotating machine with a singly excited magnetic field system as its stator and a rotor (that carries no coil) has a stator-coil inductance that can be approximated by
Q. An FM station's modulator has a sensitivity k FM = 5π × 10 4 rad/s·V. A receiver uses a discriminator that has a gain constant of 10 -5 /π V·s/rad. Neglecting noise, determin
Q A60-Hz, 100-kVA, 2400/240-V(rms) transformer is used as a step-down transformer from a transmission line to a distribution system. Consider the transformer to be ideal. (a) Fi
