Ratio of Current in Secondary to Primary
The reciprocal of the transformation ratio of a transformer is given as 11. This means that the ratio of primary voltage to secondary voltage is 11:1.
The transformation ratio of a transformer is the ratio of the number of turns in the primary winding to the number of turns in the secondary winding. It determines how the voltage and current are transformed from the primary side to the secondary side of the transformer.
Let's assume that the primary current is I1 and the secondary current is I2. We need to find the ratio of I2 to I1.
According to the transformer equation, the ratio of primary current to secondary current is equal to the ratio of secondary voltage to primary voltage. Mathematically,
I1/I2 = V2/V1
Given that the reciprocal of the transformation ratio is 11, we have V1/V2 = 11.
To find the ratio of I2 to I1, we can rearrange the equation as:
I2/I1 = V1/V2
Substituting the value of V1/V2 as 11, we get:
I2/I1 = 11
Therefore, the ratio of current in the secondary to the primary is 11:1, which corresponds to option B.
In summary:
- The reciprocal of the transformation ratio of a transformer is 11.
- The ratio of primary voltage to secondary voltage is 11:1.
- Using the transformer equation, we can find the ratio of secondary current to primary current.
- The ratio of current in the secondary to the primary is 11:1, which corresponds to option B.
