(Solved) The voltages at V1 and V2 of the arrangement shown in the figure will be respectively

 Question :

The voltages at V1 and V2 of the arrangement shown in the figure will be respectively


A. 6 V and 5.4 V

B. 5.4 V and 6 V

C. 3 V and 5.4 V

D. 6 V and 3 V


Solution :

For diode D1 it is clear that anode voltage is higher. So it is forward bias.

Voltage V2 = 6 - Vt

Vt is cut in voltage of diode.

V2 = 6 - 0.6

V2 = 5.4 V


For diode D2, cathode voltage is higher and hence it is reverse biased. 

So V1 = 6 V

So option A is correct.

Explain superposition theorem and use the principle of superposition to find the voltage Vo in the circuit

(Solved) An LVDT is connected to an amplifier of gain 250 the output terminals of which are connected to a 5 V voltmeter. The meter's scale can be read to 1/5th of a division and has 100 divisions in all. Given that a core displacement of 0.5 mm provides an output of 2 mV from the LVDT, find, 1. The sensitivity of the LVDT 2. The sensitivity of the whole system 3. The resolution of the instrument in centimeters

324 identical galvanic cells, each of internal resistance 9 ohm are arranged as several in series, groups of cell connected in parallel The arrangement has been laid out so that power output in an externally connected resistance of value 4 ohm is maximum. If n cells are connected in every series group that form parallel combination, then find value of n.
