Voltage Regulation Problems

TD A.2.1 - Transformer voltage regulation is the measure of how well the transformer maintains constant secondary voltage over a range of load currents. What is the transformer voltage regulation percentage if, at no-load, the measured transformer voltage is 7.987v and at full-load, the measured transformer voltage is 7.637V?

TD A.2.2 - A type of transformer engineered to output a nearly constant secondary voltage despite significant variations in supply voltage is known as a __________.

TD A.2.3 - Voltage regulation is a __________ between the sending and receiving end of a component, such as a transmission or distribution line. Voltage regulation describes the ability of a system to provide near constant voltage over a wide range of load conditions.

TD A.2.4 - What percent voltage regulation occurs at the receiving end of a distribution line where the voltage at no load = 12 volts and the voltage at full load = 477 volts?

TD A.2.5 - In alternating-current circuits, voltage drop is affected by impedance. Which of the following is not factored into impedance?
