Bihar Board (BSEB) Question Paper for Class 12 Physics 2018.

Q: 1. Find out the total resistance differently when four resistors each have 12Ω are connected in parallel and three 3Ω type resistors are linked in series.

For series connection, RP = 3 + 3 + 3 = 9ΩFor parallel connection, 1/RP = 1/r + 1/R + …. + n = n / R (n = no. of resistors)So, RP = R/n = 12/4 = 3Ω

Q: 2. A capacitor connected to the 200V power with parallel the parallel plates of area 6cm2 kept at a separation of 2mm. If the air between the plates acts as a dielectric medium, calculate the capacitance of the parallel plate capacitor.

Here, Area, A = 6cm2 = 6 * 10-4 m3 Separation, d = 2 mm = 2 * 10-3 mThen, Capacitance, C = (A × E0)/(d) = (6 x10-4 × 6×10-4) /(2 × 10-3)= 2.655 x 10-12 f

(Image to be added soon)

Q2. How Does the Mass of the Body React When Kept Undercharging?

Ans: After conducting numerous experiments, the charging of an object relies on the transfer of electrons. When a body starts to gain an electron, it becomes negatively charged, and its mass increases. However, when a body starts to lose electrons, and it becomes positively charged letting its mass to decrease.

Q3. How Does the Prism React When a Monochromatic Light Is Incident on It?

Ans: The light that passes through the prism will bend by the same amount.

Q4. In the Following Figure, a Magnetic Bar Is Kept Near to a Suspended Wire Loop. Where Will the Induced Current in the Loop Travel?

(Image to be added soon)

Ans: The face of the loop towards the magnet should gain polarity as per Lenz’s Law. So, the clockwise direction is seen in the loop when noticed from the sides of the magnet.

FAQs on Bihar Board (BSEB) Question Paper for Class 12 Physics 2018.

1. Find out the total resistance differently when four resistors each have 12Ω are connected in parallel and three 3Ω type resistors are linked in series.

For series connection, R_P = 3 + 3 + 3 = 9Ω

For parallel connection, 1/R_P = 1/r + 1/R + …. + n = n / R (n = no. of resistors)

So, R_P = R/n = 12/4 = 3Ω

2. A capacitor connected to the 200V power with parallel the parallel plates of area 6cm² kept at a separation of 2mm. If the air between the plates acts as a dielectric medium, calculate the capacitance of the parallel plate capacitor.

Here, Area, A = 6cm² = 6 * 10^-4 m³

Separation, d = 2 mm

= 2 * 10^-3 m

Then,

Capacitance, C = (A × E₀)/(d) = (6 x10^-4 × 6×10^-4) /(2 × 10^-3)= 2.655 x 10^-12 f

3. What remains constant in a nuclear reaction?

These are the factors that remain conserved in nuclear reactions:

Charge
Energy
momentum
Angular momentum

4. What helps to incline the value of the specific resistance of a conductor?

The rise in temperature helps to increase the value of the specific resistance of a conductor. The reason is the specific resistance of a conductor is directly proportional to the temperature of the conductor.
