Question

A transformer steps up an AC supply from 220 V to 2200 V , If the secondary coil of transformer has 2000 turns , then number of turns in Primary coil will be ?

Answer 1

200 turns ..hope it helps

no of turns proportional to voltage

Answer 2

Heya........!!!!

What is STEP UP TRANSFORMER :

➡ if the secondary coil has greater number of turns than the primary , the voltage is stepped up . This type of arrangement is called Step up Transformer .

According to The Question ::

➡ Given -

=> Number of turns in primary coil ( Np ) = ?

=> Number of turns in Secondary coil ( Ns ) = 2000

=> Voltage in primary coil ( Ep ) = 220 V

=> Voltage in secondary coil ( Es ) = 2200 V .

Now by simple formulae -> Ep/Es = Np/Ns

substituting values , we get ,,

➡ 220/2200 = Np/2000

♦=>> Np = 200 turns .

Hope It Helps You ^_^
