Answer : Option BExplaination / Solution: No Explaination.
The input impedance of the permanent magnet moving coil (PMMC) voltmeter is infinite. Assuming that the diode shown in the figure below is ideal, the reading of the voltmeter in Volts is
Answer : Option AExplaination / Solution: No Explaination.
Q4.In the circuit shown below, Q1 has negligible collector-to-emitter saturation
voltage and the diode drops negligible voltage across it under forward bias. If Vcc is +5V, X and Y are digital signals with 0V as logic 0 and Voc as logic 1, then the
Boolean expression for Z is
Answer : Option BExplaination / Solution: No Explaination.
Q5.In the summer of 2012, in New Delhi, the mean temperature of Monday to Wednesday was 41ºC and of Tuesday to Thursday was 43ºC. If the temperature on Thursday was 15% higher than that of Monday, then the temperature in ºC on Thursday was
The clock frequency applied to the digital circuit shown in the figure below is 1kHz. If the initial state of the output of the flip-flop is 0, then the frequency of the output waveform Q in kHz is
Answer : Option BExplaination / Solution: No Explaination.
Q7.A strain gauge forms one arm of the bridge shown in the figure below and has a nominal resistance
without any load as Rs = 300 Ω. Other bridge resistances are R1 = R2 = R3 = 300 Ω. The maximum
permissible current through the strain gauge is 20 mA. During certain measurement when the
bridge is excited by maximum permissible voltage and the strain gauge resistance is increased by
1% over the nominal value, the output voltage V0 in mV is
Answer : Option CExplaination / Solution: No Explaination.
