A Voltage V Is Applied to the Primary Coil of a Step-Up

question 101

Multiple Choice

A voltage V is applied to the primary coil of a step-up transformer with a 3:1 ratio of turns between its primary and secondary coils. A resistor R connected to the secondary dissipates a power P = 100 W. How much power is dissipated by the same resistor when the ratio of turns in the transformer is changed to 24:1 and the same input voltage is used?

• A)12,000 W
• B)2400 W
• C)24,000 W
• D)6400 W
• E)100 W

Morphological Convergence

The evolutionary phenomenon where organisms from different lineages develop similar anatomical features independently, usually due to similar environmental pressures.

Shared Ancestry

Shared Ancestry denotes the common genetic heritage found between different organisms or populations, underlining the evolutionary relationships that link different species or groups.

Comparative Morphology

The branch of biology that studies the structure, form, and variation of organisms to determine relationships and evolutionary changes.

Morphological Divergence

The evolution of different forms, structures, or appearances in organisms as a result of adaptation to different environments or ecological niches.
