Common Plus Two Physics Practical Viva Questions and Answers for Hsslive Students
Below are ten frequently asked questions during Plus Two Physics Practical Viva examinations along with their appropriate answers:
- Q: What is the principle of a potentiometer?
A: The potentiometer works on the principle that the potential drop across any portion of a wire of uniform cross-section is directly proportional to its length, provided a constant current flows through it.
- Q: In a galvanometer, what is the function of a radial magnetic field?
A: The radial magnetic field ensures that the deflecting torque on the coil is directly proportional to the current passing through it, regardless of the angular position of the coil. This gives a linear scale in the galvanometer.
- Q: Why is a semiconductor diode forward biased in a rectifier circuit?
A: A semiconductor diode is forward biased in a rectifier circuit because it offers low resistance to current flow in this configuration, allowing the current to pass through during the positive half cycles of AC input. This is essential for converting AC to pulsating DC.
- Q: What is the significance of using a wide-band in a P-N junction diode characteristic experiment?
A: The wide-band helps to visualize the full I-V characteristic curve of the diode across both forward and reverse bias regions. It ensures that the knee voltage and breakdown voltage can be clearly observed without changing the circuit setup.
- Q: How does a sonometer verify the laws of vibrating strings?
A: A sonometer verifies the laws of vibrating strings by demonstrating that the frequency of vibration is (i) inversely proportional to the length of the string, (ii) directly proportional to the square root of the tension, and (iii) inversely proportional to the square root of the linear density of the string.
- Q: In a meter bridge experiment, why is the jockey not slid along the wire?
A: The jockey is not slid along the wire to prevent scratching and damaging the wire, which would alter its uniform cross-sectional area. Instead, it should be gently touched to the wire at different points to find the null point without causing wear.
- Q: What precautions should be taken while using a spectrometer?
A: Key precautions include ensuring proper leveling of the spectrometer, removing parallax errors by proper focusing, using a sodium lamp for clear spectral lines, maintaining cleanliness of optical components, and taking readings from both vernier scales to minimize errors.
- Q: Why is a series combination of resistors avoided in ammeter design?
A: A series combination of resistors is avoided in ammeter design because an ammeter should have very low resistance. Adding resistors in series would increase the overall resistance, causing a significant voltage drop and affecting the circuit being measured.
- Q: Explain how you would determine the focal length of a convex lens using displacement method.
A: In the displacement method, I would place an object and screen such that a sharp image forms on the screen. Then I would note the distance between object and screen (D). The focal length (f) is calculated using the formula f = (D² – 4d²)/4D, where d is the displacement of the lens from the middle position.
- Q: What causes hysteresis in a transformer core and how can it be minimized?
A: Hysteresis in a transformer core is caused by the magnetic domains’ resistance to reorientation when the magnetizing force changes direction. This results in energy loss as heat. It can be minimized by using soft ferromagnetic materials like silicon steel, which have a narrow hysteresis loop and thus lower energy loss.
