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
