The secondary of the transformer is left open-circuited. A wattmeter is connected to the primary. An ammeter is connected in series with the primary winding. A voltmeter is optional since the applied voltage is the same as the voltmeter reading. Rated voltage is applied at primary. If the applied voltage is normal voltage then normal flux will be set up. Since iron loss is a function of applied voltage, normal iron loss will occur. Hence the iron loss is maximum at rated voltage. … WebThe instrument readings obtained in open circuit test are as follows: Ammeter reading = no-load current I 0. Voltmeter reading = primary rated voltage V 1. Wattmeter reading = …

When IN+ is higher then IN- its output transistor is turned off to become 'high impedance', so it does not draw significant current from R13. The MCU input probably also has very high impedance, so current through R13 will be very small and the voltage will be close to 3.3V. simple towel folding animals
