A. 2000 O
B. 1400 O
C. 800 O
D. 1600 O
The resistivity of the conductor depends on
A. area of the conductor.
B. length of the conductor.
C. type of material.
D. none of these.
The resistivity is a property of material, defined as the resistance between two opposite faces of a cube of a material of unit volume. That is why resistivity is only the unique property of material and it does not depend upon the dimension of any piece of material.
A. OR gates
B. NOT gates
C. NAND gates
D. None of the above
A. Two’s complement only
B. Sign and magnitude and one’s complement only
C. Two’s complement and one’s complement only
D. All three representations
A. Retardation and acceleration values
B. Gradient
C. Distance between stops
D. All of the above
A. Collector voltage is stepped up
B. resistance is low
C. collector voltage is stepped down
D. none of the above
A. Faster acceleration
B. No pollution problems
C. Better braking action
D. All of the above
