A 20 kVA, 4400/220 V transformer with an equivalent impedance of 0.01 Ω is to operate in parallel with a 15 kVA, 4400/220 V transformer with an equivalent impedance of 0.015 Ω. The two transformers are connected in parallel and made to carry a load of 25 kVA. Assume both the impedances to have the same angle.
(a) Find the individual load currents.
(b) What per cent of the rated capacity is used in each transformer?
For the network of given figure, VL must be 8 V before the system is activated. If the switch is closed at t = 0 s, how long will it take for the system to be activated?
Consider a digital communication system in which the received symbol y is equal to : y = x+I+n, where n is AWGN with variant sigma_n^2, I models interference independent of both x and n and x is the data taking values +A and -A.
A gas mixture contains 5 kg of N2 and 10 kg of O2. Determine the average molar mass and gas constant. What-if-scenario: How would the conclusion change if the gas mixture contained 10 kg of N2 and 5 kg of O2
If an ammeter reads 2.5 A for a period of 4 min, determine the charge that has passed through the meter.
What is the relationship between the opportunity cost of acommodity and the relative price of that commodity?How can they be visualizedgraphically?
calculate the potential variation vx electric field and the depletion layer width for a graded p-n junction that is
The periodic current waveform of given figure is composed of segments of a sinusoid. Find the average value of the current.
Assume that the memory locations M[$20], M[$21] and M[$22]. Write a 68HC11 assembly language program (with lots of comments) that will determine the sum of the largest two numbers and store its value in M[$23].
Numerous studies have shown that there is usually a systematic relationship between concentration and price. What is this relationship? Offer two brief explanations for this relationship.
It was said in the text that transformers suffer eddy current as well as hysteresis losses. What other types of losses can be expected in a transformer? How can those losses be reduced?
Historically op amps and comparators have a lot of similarity in their internal circuit designs. However, they have very different uses in application circuits. Let's talk about these differences.
