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.
A heater element is made of nichrome wire having resistivity equal to 100 × 10 -8 ohm-m. The diameter of the wire is 0.4mm. Calculate the length of the wire required to get a resi
Factors Affecting High Commercial Losses Commercial losses in our country occur mainly because of the following reasons: Incorrect assessment of the energy consum

Magnetic permeability and the B/H curve To measure the relationship between field strength H and flux density B for a material, a sample is made into a closed ring and a magne
Q. Sketch the idealized (asymptotic) Bode plot for the transfer function Find the angular frequency at which H(ω) is 0dB and the angular frequency at which θ(ω) = -60°.
You should document each step of each iteration of your design. 1. You should include the following items from your preparation. a. A state diagram of the handshaking receive
