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.
Q. If a feeder circuit-breaker trips, what action is needed? Ans: First isolate the faulty feeder check the faulty area on which fault the breaker was tripped (open circuit,
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
Define the term real time clock. A real-time clock maintains the time in real time, which is, in hours and minutes. For the real-time clock the software contains an interrupt
Q. What is Discrete signals? Discrete signals, on the other hand, exist only at specific instances of time, and as such, their functional description is valid only for discrete
The FESTO conveyer consists of 600mm belt driven by a 24V d.c. motor at a rate of 13 seconds per metre. A relay on the FESTO panel controls the motor operation and is wired for sou
Q. What do you mean by Blocking Probability? Blocking Probability:Blocking probability P is defined as probability that all the servers in system are busy. When all servers are
Why is the signal first attenuated and then amplified?
Q. What is right-through routing? In right-through routing, originating exchange determines complete route from source to destination. No routing decisions are taken at interme
