Extracted text: Q.1: The following data refer to a single-phase transformer: Turn ratio (2:1). R1-2.4 n. X-5.5 0. R-0.6 n. X-1.70. The no-load current 1.5A keading the flux (@) by 25". The primary current is 16A and the input voltage is 372V and power input factor 0.65 kagging. Determine by aid of a vector diagram. (i) the load voltage and current, (ii) the load power factor, (ii) the efficiency.
