Please help me with this assessment ( Transformer )
Please help me with this assessment
A STIEBEL ELTRON water heater model DHC4-3 is designed to operate at 277V AC to generate heat energy at a rate of 4.5kW. The main AC supply is sinusoidal with amplitude 312V at 50Hz.
(i) what is the turns ratio of the transformer required?
(ii) what is the resistance of the heater coil?
(iii) If the resistance of the heater coil increases by 1.08 times after 5 minutes of use due to the increase in temperature, what would be the rate of energy consumption (in kW) by the heater coil?
(iv) Assuming step-change in the resistance value and if the heater is operated for 8 minutes at a rate of cents 16.01 per 1kW-h, what will be the cost (in cents) incurred?
i) So you need a transformer to change 312 volts to 277 volts. This is a transformer with a turns ratio of 312 to 277
ii) P = E²/R
4500 = 277²/R
R = 17.05 ohms
iii) 17.05 x 1.08 = 18.41 ohms
P = E²/R = 277²/18.41 = 4167 watts
iv) Step change, so it operated 5 minutes at 4500 watts, which is
4500 W x 5 min x 1hr/60min = 375 W-hr or 0.375 kW-hr
(corrected error in line above)
The next 3 minutes, is is using 4167
4167 W x 3 min x 1hr/60min = 208 W-hr or 0.206 kW-hr
Adding the two, 0.583 kW-hr
multiplying by 16.01¢ = 9.3¢
edit: "retired", you could be right about the 312 volts, although it is usually listed as "312 volts peak". I always assume RMS unless stated otherwise. Found the arithmetic error, thanks.

Top Selling Tankless Water Heaters - Titan Tankless Water Heaters 3 years in a row
1. Titan Tankless Water Heaters
Titan Tankless Water Heaters easily took the number one spot again (3 years in a row) for the best electric tankless models. The company has been in business going on 24 years and developed much of the technology other companies use today. The product is made in the USA and has the best warranty with 10 years on internal water carrying components. The price of the standard home model, which is the Titan SCR2 - N120 model, is by far the best value with a price of $249.99. Comparable models from competitors can range from $400-$800 dollars and can not match the quality. The Titan has all steel construction (many are plastic) with the best internal components to resist hard water, mineral deposits etc. They have many different size models depending on your needs and emergency overnight shipping. The internal computer technology is reliable complex, advanced and is currently being shared by NASA in their programs. They get the number one spot based on being the most senior company and best over all quality.
2. Stiebel Eltron
The Stiebel with its Tempra line has moved up to number two this year on our list. Their technology is similar to the Titan and shares an all steel construction as well. The units are reliable and withstood all pressure and output tests. They currently offer a 3 year warranty on their product line and have some of the best hot water output production in the electric line. The downfall of these units is they can be pricey and have a 3 year warranty. They are also originally from Germany so parts can be hard to come by. They do have an office in the USA now so this problem has been alleviated.
3. Powerstar Tankless Water Heaters - Bosch
The Powerstart models are made by Bosch, the company involved in the gas Tankless recall. Despite this fact they make a quality Tankless electric models as well. These models can be found at some Home Depot stores. They offer a 5 year warranty on their products. The model performed well in testing but did have some short comings. The outer casing is plastic and the temperature ranges were not adjustable like the Titan and Stiebel models. The prices offered for these units are fair and the customer service offered is excellent. Again another Tankless unit with dozens of websites selling the product. We find the best and most reliable to be good old Home Depot:
