In figure the total inductance of the circuit is
Answer: Option
Explanation:
Inductances are in series aiding connection. M terms will become twice because of mutual inductance between L1 and L2 and that between L2 and L1.
42.
In the network of figure, the voltage drops across R1, R2, R3 are 6 V, 8 V and 12 V with polarities as shown. The value of R3 is
Answer: Option
Explanation:
From the given data the current through R1 is 4 A.
43.
Assertion (A): Millman's theorem helps in replacing a number of current sources in parallel by a single current source.
Reason (R): Maximum power transfer theorem is applicable only for dc, circuits.
Answer: Option
Explanation:
Maximum power transfer theorem is applicable to ac circuits.
44.
Double integration of unit step function leads to
Answer: Option
Explanation:
Integral of unit step function is ramp and integral of ramp is doublet.
45.
A conductor has a cylindrical shape with a diameter d. Its resistance is 2 Ω. It is recast into a cylindrical conductor of diameter 0.3d. The resistance of new conductor is likely to be
Answer: Option
Explanation:
Since new diameter is 0.3 d, the new area of cross-section a (0.3 d)2.
The volume remains the same. Therefore length increase by a factor 
.
Hence
