TS EAMCET Mock Test - 5 - Question 1

The current gain for a transistor working as common-base amplifier is 0.96. If the emitter current is 7.2 mA, then the base current is

Detailed Solution for TS EAMCET Mock Test - 5 - Question 1
- The current gain (α) for a common-base amplifier is given as 0.96.
- The emitter current (Ie) is 7.2 mA.
- The relation between emitter current and base current (Ib) is: Ib = Ie * (1 - α).
- Substituting the values: Ib = 7.2 mA * (1 - 0.96) = 7.2 mA * 0.04 = 0.288 mA.
- Rounding off gives approximately 0.29 mA, which corresponds to option 1.
TS EAMCET Mock Test - 5 - Question 2

A capacitor of 10 μF charged up to 250 volts is connected in parallel with another capacitor of 5 μF charged up to 100 volts. The common potential is

Detailed Solution for TS EAMCET Mock Test - 5 - Question 2
- First, calculate the initial charge on each capacitor using the formula Q = C × V.
- For the 10 μF capacitor: Q1 = 10 μF × 250 V = 2500 μC.
- For the 5 μF capacitor: Q2 = 5 μF × 100 V = 500 μC.
- Total charge after connecting in parallel: Q_total = Q1 + Q2 = 2500 μC + 500 μC = 3000 μC.
- The total capacitance in parallel: C_total = 10 μF + 5 μF = 15 μF.
- Finally, find the common voltage: V_common = Q_total / C_total = 3000 μC / 15 μF = 200 V.
- Therefore, the common potential is 200 V.

TS EAMCET Mock Test - 5 - Question 7

A ray of light is incident at 60o on a prism of refracting angle 30o . The emergent ray is at an angle 30o with the incident ray. The value of refractive index of the prism is

Detailed Solution for TS EAMCET Mock Test - 5 - Question 7

Angle of prism = 30o = A
Angle of incidence = i1 = 60o
Angle of emergence = i2 = ?
Angle of devation = D = 30o
∴ i2 = A + D - i2 = 30 + 30 - 60 = 0o
⇒ r2 = 0o
∴ r1 = A-r2 = 30 - 0 = 30o
∴ μ = sin i 1 sin r 1 = sin 60o /sin 30o = √ 3
