96. The voltage output of an ideal induction coil of 1 m^2 area and 50000 turns with a sinusoidal excitation of 1 gamma peak to peak amplitude at 10 Hz frequency is 314.1 micro volt. What will be the voltage at 0.1 Hz?
A) 31.41 micro volt
B) 3.141 micro volt
C) 0.314 micro volt
D) 0.0314 micro volt
Answer: B
Solution:
The amplitude is 314.1 micro volt at frequency is 10 Hz
What is the amplitude at frequency is 0.1 Hz
cross multiplication,
314.1 micro volt --------------10Hz
X------------------------------------ 0.1Hz
X = (314.1 * 0.1) / 10
X = 3.141 micro volt
Therefore, the amplitude is 3.141 micro volt at frequency 0.1 Hz
