Question

Find the value of voltage in the bandwidth range when the maximum value of voltage is 100 V.

(a) 56.65 V

(b) 35.36 V

(c) 45.34 V

(d) 70.72 V

I had been asked this question during an internship interview.

My question comes from Bandwidth in division Resonance in AC Circuits of Basic Electrical Engineering

Answer 1

Correct choice is (d) 70.72 V

To elaborate: At the bandwidth frequency range, the value of the voltage is equal to the maximum value of voltage divided by √2. Hence V =100/√2= 70.72V.
