Model paper for BSNL JTO ECE
I am looking for BSNL JTO for Electronics and Communication question papers, will you please provide here??? Here are BSNL JTO for Electronics and Communication question paper: 1. Q-meter works on the principle of a. series resonance b. parallel resonance c. mutual inductance d. self inductance 2. The bridge circuit shown in Fig. Q2-I a. cannot be balanced b. can be balanced but the frequency of excitation must be known c. can be balanced for only one frequency d. can be balanced at any frequency 3. Which one of the following statements is TRUE for an ‘ideal’ power diode? a. Forward voltage drop is zero and reverse saturation current is non-zero. b. Reverse recovery time is non-zero and reverse saturation current is zero. c. Forward voltage drop is zero and reverse recovery time is zero. d. Forward voltage drop is non-zero and reverse recovery time is zero. 4. In a MOSFET, the pinch-off voltage refers to a. drain-to-source voltage at which drain-tosource current is zero b. gate-to-source voltage at which gate-tosource current is zero c. drain-to-source voltage at which gate-tosource current is zero d. gate-to-source voltage at which drain-tosource current is zero 5. Which of the following statements is TRUE for DC switched mode power supply? a. It cannot provide isolation between input and output as in rectifiers. b. It cannot remove ripple as in DC switching mode regulators. c. It has two stage conversions: dc-ac and acdc. d. It is a type of chopper circuit.
