## Class 12 Physics Study materials – Free Download

This will reduce the number of final board examination days. Books have been colleagues of youth for a long time.

They have served humankind from times obscure. Books have opened a vista to the wide entryway of learning, instruction, investigation and information.

## Featured Simulation

We not just gain from a book, book additionally improves our capacity of creative energy. NCERT books are the books that score an unmistakable full stamp with regards to satisfying the previously mentioned criteria. They are unmistakably the best educative books you can lay your hands on. It resembles as though you are educated by an individual coach.

The writings are informed with ends; this encourages the understudy to look upon the primary features without experiencing the whole content. The frequency of the A. Junction diode Forward bias 1.

## "+relatedpoststitle+"

For various forward voltages , the forward current is measured and the readings are tabulated. A graph is plotted by taking along X —axis and along Y — axis.

The forward voltage of the diode is calculated from reciprocal of the slope of the graph using the formula II.

For various voltage , the corresponding zener current is measured and the readings are tabulated. Zener breakdown voltage is calculated from the graph.

Draw the input characteristic and output characteristic curves. Find the input impedance and output impedance.

A graph is plotted by taking along X — axis and along y — axis. The input impedance is calculated from the reciprocal of the slope of the curve using the formula 2.

For various values of , is noted and the readings are tabulated. The output impedance is calculated from the reciprocal of the slope of the curve using the formula www. No IC mA 0. The input and output characteristic curves of the transistor in CE configuration are drawn.

Draw the output characteristic and transfer characteristic curves. Find the output impedance and current gain.

The output impedance is calculated from the reciprocal of the slope of the curve using the formula 2. The output and transfer characteristic curves of the transistor in CE configuration are drawn.

Using IC , construct i an inverting amplifier ii summing amplifier study their performance Connections are made as shown in the circuit diagram. For various input voltages Vin , the corresponding output voltages V0 is measured and the readings are tabulated.

The voltage gain calculated as : Experimental gain and the theoretical gain 6. The experimental value is compared with the theoretical value and the inverting action is verified.

For various values of VI and V2 the corresponding output voltage Vo is measured and the readings are tabulated. Thus the summing action of the amplifier is verified. Using IC , construct i non- inverting amplifier ii summing amplifier study their Performance. Voltage gain of the non-inverting amplifier, 2. The experimental value is compared with the theoretical value and the non-inverting action is verified.

Then the experiment is repeated for different sets of values for V1 and V2. Since this is equal to experimental output voltage the summing action of the amplifier is verified.

## An Exemplary Viva Voce (CBSE Class XII Physics Practical)

The summing amplifier is constructed and the output voltage is found to be the sum of the applied input voltages www. IC is placed on the board.

The two logic select input switches are connected to the input pins.Are you sure you want to Yes No. Share with Friends. These books are all around educated and impartial. Previously there were two papers for each subject in class The point J where the galvanometer wire shows full scale deflection is noted.
