1) A transformer has a primary side that contains 1500 turns and it is connected to 120V AC. If a motor connected to the transformer requires 7.5A at 24V, find, (a) the number of secondary turns required. (b) the primary current. 2) A single-phase transformer is rated as 250V, 100A. The transformer has copper losses of 450W and iron losses of 225W. Determine the transformer efficiency at full load and 0.8 power factor, PF.

Whats are the trickiest steps to do when adding or subtracting rational expressions? how does knowledge of rational numbers u in adding and subtracting rational expressions?

Select all of the following expressions that are equal to 2.5.

He graph of f(x) = |x| is stretched by a factor of 0.3 and translated down 4 units. which statement about the domain and range of each function is correct? the range of the transformed function and the parent function are both all real numbers greater than or equal to 4. the domain of the transformed function is all real numbers and is, therefore, different from that of the parent function. the range of the transformed function is all real numbers greater than or equal to 0 and is, therefore, different from that of the parent function. the domain of the transformed function and the parent function are both all real numbers.
