If magnetic flux through each turn of the coil consisting of 1000 turns is, where t is in seconds, then the induced emf in coil at is

In an n-type semiconductor, the Fermi level lies 0.3eV below the conduction band at 300K. If the temperature is increased to 350K, then the Fermi level lies at what ‘eV’ below the conduction band. Assume density of states is constant with temperature.

Consider two statistically independent zero mean random processes and with auto correlation functions and.

If, then the value of

Alloy steel which is work harden able and which is used to make the blades of bulldozers, bucket wheel excavators and other earth moving equipment contain iron, carbon and

Consider a single level cache with an access time of 2.5 nsec a line of 64 bytes and a hit ratio is 0.95 . Main memory uses a block transfer capability that has a first word i.e. 4 bytes access time of 50 nsec and after that 5 nsec for each word access. If cache wait until block copy from main memory to cache and then access from cache, the access time is

The voltage and current drawn by a resistive load are measured with a 100 V voltmeter of accuracy ± 1% of full scale and a 25 A ammeter of accuracy ± 0.5% of full scale. The readings obtained are 50 V and 12.5 A. The limiting error (in %) in computing the load resistance is _____
