Question

In a transformer with no bar inside, the frequency of primary is ....... Secondary and there .......... a phase shift in voltage.

a) Higher, will not be b) smaller, will not be c) equal, will be d) equal, will not be

Answer 1

Transformer is the static device which is use to transform the voltage or current . There are two types of transformer steup up and step down

Now one important property of the transformer is frequency always remains same . Frequency will not change . There primary side frequency as equal to the secondary side frequency .

When primary Ac voltage is apply to the transformer there is phase shift of voltage at secondary side .

Hence option C is correct answer .
