Question

Write the voltage ratio formula = _____ b) Write the current ratio formula = _______ c) Write the turns ratio formula = _______ d) Primary number of turns in step up transformer is higher than the secondary turns. True _____ or False ______ e) Primary number of turns in steps down transformer is lower than the secondary turns. True _____ or False ______ f) The primary current value is equal to ______ amps g) The secondary voltage is equal to _____ volt. h) The total power in the primary winding equals _____ watts i) The input winding of a transformer is called the ______

Explanation / Answer

a). Voltage ratio formula = V2/V1 where V2 = Secondary/ Output Voltage and V1= Primary/Input Voltage...... b). Current ratio formula = I2/I1 where I2= Secondary current and I1= Primary Current...... c). Turn ratio Formula = T2/T1 where T2 is number of turns in the secondary winding and T1 is the number of turns in the primary winding....... d). False. Step up transformer has high voltage in the secondary winding. And Voltage is proportional to number of turns. Thus number of turns will be higher in the secondary winding........ e) . False. Step down transformer has low voltage in the secondary winding. And Voltage is proportional to number of turns. Thus number of turns will be lower in the secondary winding........ f) we know that v1/v2= n1/n2= Is/Ip Or 1/Ip= 10/1 or Ip= 0.1 ....... g) From v1/v2= n1/n2 we have 60/v2= 10/1 or v2 = 6 V ................h) Power is defined as V*I for primary winding V= 60v and Ip= 0.1 A Thus power = 60*0.1 = 6 Watt....i) Input winding is called Primary Wnding.
