Question

What is the rms value of output current if the peak value of output current is given as 0.092 A?

(a) 0.65 A

(b) 6.5 A

(c) 0.45 A

(d) 0.065 A

I have been asked this question in an internship interview.

This interesting question is from Semiconductor Electronics topic in section Semiconductor Electronics : Materials, Devices and Simple Circuits of Physics – Class 12

Answer 1

The correct answer is (d) 0.065 A

For explanation: Given: I0 = 0.092 A

The required equation is ➔ Irms = \(\frac {I_O}{\sqrt {2}}\)

Irms = \(\frac {0.092}{1.414}\)

Irms = 0.065 A
