Write a note on superconductors.
Superconductors- The resistivity of most metals rises with increase in temperature and vice-versa. Some metals and chemical compounds are there, whose resistivity becomes zero while their temperature is brought near 00Kelvin (-2730C). At that stage these metals or compounds are be have attained superconductivity. Illustration - mercury becomes superconducting at about 4.5 Kelvin (-268.50C). Superconductivity was discovered through Heike Kamerlingh Onnes. The transition make normal conductivity to superconductivity takes place almost rapidly; this occurs over a very narrow range of temperature regarding 0.050K. The temperature at that the transition takes place from the state of normal conductivity to that of superconductivity is termed as transition temperature. Superconductors are utilized for producing very magnetic fields of approximately 50 Tesla. Magnetic energy can be stored in huge superconductors and drawn as needed to counter the voltage fluctuations throughout peak loading. Superconductors can be utilized to perform logic and storage functions in computers. Since there is no, I2R losses in a superconductor, therefore power can be transmitted by the superconducting cables without any losses. Superconducting property can be vanished by applying external magnetic field as in figure (b). In figure (b) HC is critical magnetic field and TC critical temperature.

Q. Consider a BJT switch connected to the next stage, as shown in Figure, in which iout is likely to be negative when v out is high. Assume V CC = 5 V, R C = 1k, and the high r
Give the properties and application of cotton. Cotton : It is base material for insulating fibres. Properties: It can be enhanced by impregnating with varnish. 1)
Q. In an RLC series circuit excited by a voltage source v(t), for R = 10 , L = 1 H, and C = 0.1F, determine v(t) if the capacitor voltage vC(t) = 5e -10t V.
Indirect Addressing In this addressing mo e also ne of the operands is the stored in the memory. The memory address of the operand is specified by the register pair.
What is resistivity? Resistivity of a material may be explained as the resistance of the material having unit length and also unit cross sectional area. Unit of it is ohm-m.
Number Systems Various number systems are decimal ( used by human beings) binary ( used by digital systems) octal and hexadecimal (used to represent binary numbers in small
