Question

Which equation is incorrect for transformer? 
A. V1/V2=E1/E2
 B. V1/V2=I1/I2 
C. V1/V2=N1/N2 
D. V1/V2=I2/I1 ​

Answer 1

Answer:

B

Explanation:

there are different cases

1.in case of current and voltage --->v1/v2=I2/I1

2.In case of voltage and number of widennings---->v1/v2=N1/N2

3.In case of current and number of widenings---->I1/I2=N2/N1
