Question

In a step -up transformerwhich of the following is decreased (a)Voltage (b) Current (c) Wattage (d) None of these

Answer 1

Answer:

In a STEP UP TRANFORMER there is in increase in Voltage takes place

Explanation:

THERE IS two kinds of transformer :

 1 Step up

 2 Step down

STEP UP :

 In step there is lower no of turns in primary as compared to secondary coil and vice versa in step down ...

BASICALLY ,

what is Transformer ?

   an apparatus for reducing or increasing the voltage of an alternating current ....

FOR SENDING PURPOSES :

The transformer can transform the Voltage:Current ratio but it can't create more power. In fact, there is always some loss. Power doesn't magically appear so if the output voltage increases, then the output current must decrease in order for the power to remain the same.

SO ONLY VOLTAGE WILL BE INCREASED IN STEP UP ..

HOPE SO THIS ANS WILL HELP U SO PLZ BRAINLIST THXXXXX:)
