Question One 1. Starting with differentiating a transducer from a sensor, explain the operation principle of a piezoelectric transducer and its main application in our day to day life. 2. With the aid of an illustration, clearly explain the operation principles of a CRO and its main applications. 3. A 3 phase I MVA load has a PF of 0.9. If the power consumed by it was measured by two wattmeter method, find the reading of each wattmeter (i) when the PF is leading, (ii) when PF is lagging. Question Two 1. An inductive load takes a current of 5 A, a non-inductive resistor connected in parallel take a 3 A when connected across a 230 V supply. The total current taken from the supply is 10 A. Calculate the power consumed of the load, load impedance and power factor of the load. 2. With equivalent circuits and phasor diagrams, derive the expression for total power consumed by balanced three load measured by two wattmeter method and the power factor if the Load is delta connected and power factor is lagging. 3. The resistance of a thermistor is 800NT 60 °C and 5 kn at freezing point. Calculate the characteristic constants (A, B) for the thermistor and variations. in resistance between 30 °C to 100 °C. Question Three 1. What is the resolution of 3 digital display of I V and 10 V ranges? A 3 digital voltmeter has an accuracy specification of +/- 0.5 % of reading+/- I digit. What is possible error in volts when the instrument reading 3.54 V on 5 V scale. 2. With an illustration explain the functions of individual components of a PLC 3. With a block diagram explain for the digital multi-meter operate when measuring AC voltage, DC voltage, AC current, DC current and Resistance.
