Consider two transformers A and B having exact ratings, but have flux ...
Explanation:
To determine the weight per KVA for transformers A and B, we need to consider the relationship between flux density and weight.
Flux density:
Flux density is a measure of the magnetic field strength within the core of a transformer. It is denoted by the symbol "B" and is measured in teslas (T).
Weight per KVA:
The weight per KVA is the weight of the transformer per unit of apparent power (KVA). It is a measure of the size and materials used in the construction of the transformer.
Relation between flux density and weight:
The weight of a transformer is directly influenced by the flux density. Higher flux density requires more magnetic material in the core, resulting in a heavier transformer.
Comparison of transformers A and B:
Given that transformer A has a flux density of 1.5T and transformer B has a flux density of 2T, we can conclude the following:
1. Transformer B has a higher flux density than transformer A.
2. Due to the higher flux density, transformer B will require more magnetic material, resulting in a higher weight.
Therefore, the weight per KVA of transformer A will be less than that of transformer B.
Hence, the correct answer is: Option B) Lesser than that of B.

Consider two transformers A and B having exact ratings, but have flux ...
Flux density = flux/Area.
Hence A has more area than B and so weight of A will be more than that of B.
Hence A has more area than B and so weight of A will be more than that of B.
