A step up transformer has transformation ratio of 3:2. what is the voltage in secondary if the primary voltage is 30V.
Correct answer: B. 60V
- A. 20V
- B. 60V
- C. 45V
- D. 15V
Explanation
The transformation ratio of a transformer is given by the ratio of the number of turns in the secondary coil to the number of turns in the primary coil. In this case, the transformation ratio is 3:2, which means the secondary voltage (V) is greater than the primary voltage (V).The voltage in the secondary (V) can be calculated using the formula:V8 /VP = N8 / NPGiven that the transformation ratio is 3:2, the number of turns in the secondary (N) is 3, and the number of turns in the primary (N) is 2. Therefore:V8 / 30 =3/2Solving for V :V=3/2 X30=60VTherefore the correct answer is (b) 60v

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
