    Help with transformer

    Hello nutty boy! Here goes an experiment to measure max output current. 1. Measure o/p voltage or trafo as V1. 2. Put a high wattage low value variable resistance (better use  Rheostat) with max resistance. 3. Decrease load resistence untill you get half of V1 (i.e. V1/2) 4. Take...

    Variable AC Dummy Load

    Hello Xenobius! I can remember something about the transformer properties.  IT says To change the voltage level v1= (n1 / n2 )*v2 v1=secondary volts v2=primary volts n1=secondary  turns n2=primary turns similarly it transfers impedence to the other side by! Z1 = Z2 * (n1 / n2)^2 Z2 =...
