Question

Calculate peak-peak voltage if Vmax=45 V and Vmin=45 V.

(a) 60 V

(b) 30 V

(c) 50 V

(d) 0 V

The question was posed to me in a job interview.

Enquiry is from Solid State Controlled Drives topic in chapter Introduction to Solid State Controlled Drives of Electric Drives

Answer 1

The correct choice is (d) 0 V

To elaborate: Peak-Peak voltage is equal to the difference between the maximum and minimum voltage. It is mathematically represented as Vp-p=Vmax-Vmin=45-45=0 V. It signifies the signal is DC signal.
